Mount Vernon is a historic national landmark and former plantation of the first president of the United States, George Washington and his wife, Martha. The estate is on the banks of the Potomac River in Fairfax County, Virginia. It is located south of Washington, DC and Alexandria, VA and across the river from Prince George's County, MD.

The Washington family acquired land in the area in 1674. Around 1734, the family embarked on an expansion of its estate that continued under George Washington, who began leasing the estate in 1754 before becoming its sole owner in 1761.

The original mansion was built around 1734 by George Washington's father, Augustine. George Washington expanded the house twice, once in the late 1750s and again in the 1770s. It remained Washington's home for the rest of his life. Following his death in 1799, under the ownership of several successive generations of the family, the estate progressively declined as revenues were insufficient to maintain it adequately. It wasn’t until 1858 that the house’s historical importance was recognized and saved from ruin by the Mount Vernon Ladies' Association.

The pecan tree featured below was removed in Jan 2014 due to the risks of the tree damaging the Mansion. George Washington did not plant this tree. He didn't have any trees of this size close to his home. It is believed the pecan tree was planted about 60 years after he passed away, around 1860, making it an estimated 154 years old. The tree stood approximately 145 feet tall and weighed an estimated 50 tons.

The Polo Grounds was the name of three stadiums in Upper Manhattan, New York City, used mainly for professional baseball and American football from 1880 until 1963. As the name suggests, the original Polo Grounds, opened in 1876 and demolished in 1889, was built for the sport of polo. Bound on the south and north by 110th and 112th Streets and on the east and west by Fifth and Sixth (Lenox) Avenues, just north of Central Park, it was converted to a baseball stadium when leased by the New York Metropolitans in 1880. The third Polo Grounds, built in 1890 and renovated after a fire in 1911, is the one generally indicated when the Polo Grounds is referenced. It was located in Coogan's Hollow and was noted for its distinctive bathtub shape, very short distances to the left and right field walls, and an unusually deep center field.

In baseball, the original Polo Grounds was home to the New York Metropolitans from 1880 until 1885, and the New York Giants from 1883 until 1888. The Giants played in the second Polo Grounds for part of the 1889 season and all of the 1890 season, and at the third and fourth Polo Grounds from 1891 through 1957. The Polo Grounds was also the home field of the New York Yankees from 1913 until 1922 and the New York Mets in their first two seasons of 1962 and 1963. It hosted the 1934 and 1942 Major League Baseball All-Star Games.

In football, the third Polo Grounds was home to the New York Brickley Giants for one game in 1921 and the New York Giants from 1925 to 1955. The New York Jets of the American Football League played at the stadium from the league's inaugural season of 1960 through 1963.

Other sporting events held at the Polo Grounds included soccer, boxing, and Gaelic football. The last sporting event at the Polo Grounds was a football game between the New York Jets and the Buffalo Bills on December 14, 1963. Shea Stadium opened in 1964 and replaced the Polo Grounds as the home of the Mets and Jets. The Polo Grounds was demolished over a period of four months that year and a public housing complex, known as the Polo Grounds Towers, was built on the site.

Isle Casino Racing Pompano Park, more commonly known simply as Pompano Park, is a standardbred harness racing track and casino in Pompano Beach, Florida. It is billed as "The Winter Home of Harness Racing," as its tropical South Florida location makes it an ideal alternative for horsemen, when most of the racetracks to the north are subject to racing in snow, ice and bitter cold conditions. The track operates its live racing meet for about ten months out of every year, with a short break during the last half of June through the second week in August.

Like most racetracks, Pompano simulcasts horse races from all over the USA and Canada, allowing its patrons to wager on racing approximately 363 days per year. Pompano Park is owned and operated by Eldorado Resorts.

The track has been converted into a "racino" with slot machines. It currently offers live poker games, under betting limitations imposed by Florida law.

In 2018, Eldorado Resorts announced a joint venture with the Cordish Companies to develop the area surrounding Pompano Park with a mixed-use project including retail, dining, office, residential, and hotel elements.

The seat wood was from Pompano Race Track and original most were painted red, but some were painted orange or yellow too. These seats were used in the movie "42", which was about the life Jackie Robinson. The movie production company Warner Brothers had them all painted blue/grey to match Ebbets Field colors.

Blanks are from wood spokes salvaged from an original wood spoke wheels of a 1929 Pontiac Big Six.

Pen Blanks are a minimum of 3/4" x 3/4"

All blanks will come with one COA per blank.

Pontiac was an American brand of automobiles owned, manufactured and commercialized by General Motors. Introduced as a companion make for GM's more expensive line of Oakland automobiles, Pontiac overtook Oakland in popularity and supplanted its parent brand entirely by 1933.

Pontiac was advertised as the performance division of General Motors from the 1960s onward and sold in the United States, Canada, and Mexico. In the hierarchy of GM's five divisions, it slotted above Chevrolet, but below Oldsmobile, Buick, and Cadillac.

The Pontiac brand was introduced by General Motors in 1926 as the companion marque to GM's Oakland division, and shared the GM A platform. Purchased by General Motors in 1909, Oakland continued to produce modestly priced automobiles until 1931, when it was renamed Pontiac. It was named after the famous Ottawa chief, who had also given his name to the city of Pontiac, Michigan, where the car was produced.

Amid late 2000s financial problems and restructuring efforts, GM announced in 2008 it would follow the same path with Pontiac as it had with Oldsmobile in 2004 and discontinued manufacturing and marketing vehicles under that brand by the end of 2010. The last Pontiac-badged cars were built in December 2009, with one final vehicle in January 2010.

These blanks are from the hickory wooden 12-spoke wheel of a 1926 Pontiac Big Six 6-29. Total production of the New Big Six between January and the end of July of 1929 was 120,000 units. In August 1929, Pontiac switched to the New Series Bix Six 6-29A with easy to spot wooden 10-spoke wheel. The wood is certified and distributed by Hardin Penworks, LLC.

The Pontiac Silverdome or more commonly Silverdome, was a stadium in Pontiac, Michigan. It opened in 1975 featureing a fiberglass fabric roof held up by air pressure, the first use of the architectural technique in a major athletic facility. With a seating capacity of 82,000+, it was the largest stadium in the NFL at that time. It was primarily the home of the NFL Detroit Lions from 1975 to 2001 and the NBA Detroit Pistons from 1978 to 1988.

Progressive Field is a Major League Baseball (MLB) baseball park located in the downtown area of Cleveland, Ohio, United States. It is the home field of the Cleveland Guardians and, together with Rocket Mortgage FieldHouse, is part of the Gateway Sports and Entertainment Complex.[9] It was ranked as MLB's best ballpark in a 2008 Sports Illustrated fan opinion poll.

The ballpark opened as Jacobs Field in 1994 to replace Cleveland Stadium, which the Guardians, then known as the Cleveland Indians, had shared with the Cleveland Browns of the National Football League. Since 2008, the facility has been named for Progressive Corporation, based in the Cleveland suburb of Mayfield, which purchased naming rights for $58 million over 16 years. The previous name came from team owners Richard and David Jacobs, who had acquired naming rights when the facility opened. The ballpark is still often referred to as "The Jake" based on its original name.

Purple Heart Wood Pen Blanks – 5" × ¾" Square

Scientific Name: Peltogyne spp. Common Names: Purpleheart, Amaranth, Roxinho, Violeta, Pau Roxo

Origin

Purpleheart is a striking exotic hardwood native to the tropical rainforests of Central and South America. It grows from Mexico through Central America and down into northern South America, including Brazil, Colombia, Venezuela, and Suriname. These impressive trees can reach heights of 100–150 feet (30–45 m) and yield dense, vibrant timber prized by woodturners and craftsmen worldwide.

Description & Characteristics

True to its name, Purpleheart is famous for its vibrant, natural violet-to-deep-purple heartwood. When freshly cut, the color is often more muted (reddish-brown to salmon), but it dramatically shifts to rich purple upon exposure to light and air. Over time and with UV exposure, it can darken to a chocolate brown, giving finished pens a unique aging character. It features a fine, uniform texture with mostly straight grain (occasionally wavy or interlocked), producing a smooth, lustrous finish that highlights its bold color.

These premium 5" × ¾" square pen blanks are kiln-dried, pre-squared, and hand-selected for vibrant color and minimal defects. They turn into eye-catching pens that stand out in any collection — perfect for bold, modern, or statement pieces.

Turning Tips for Purple Heart Wood

• Color & Figure: The signature purple hue creates dramatic, high-contrast pens. The color intensifies with light exposure but may shift to brown over years — a natural trait that adds character.
• Workability: Very dense and hard (Janka hardness typically 1,860–2,520 lbf). Use sharp carbide or HSS tools at moderate speeds (1,800–2,500 RPM) to avoid overheating, which can cause gummy resin buildup or burning. It turns cleanly when sharp but can show tear-out in end grain — take light cuts. Has a mild, pleasant scent while turning.
• Sanding & Finishing: Sands beautifully to a glass-smooth finish and accepts most pen finishes exceptionally well (CA glue, epoxy, friction polish, etc.), resulting in a deep, glossy luster.
• Dust & Safety: Produces fine dust — always use good dust extraction and a respirator. Extremely durable and stable once finished.

Ideal for pen makers who want a bold, exotic look with exceptional strength and longevity. Purpleheart pens feel substantial, turn heads, and develop a rich patina that tells a story.

Sierra and Bolt embedded blanks with RAF F.4 Buzzard wood .

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The Martinsyde F.4 Buzzard was developed as a powerful and fast biplane fighter for the Royal Air Force (RAF), but the end of the First World War led to the abandonment of large-scale production. Fewer than 400 were eventually produced, with many exported. Of particular note was the Buzzard's high speed, being one of the fastest aircraft developed during World War I.

Sierra and Bolt embedded blanks with WWII RAF Gloster Gladiator Mk. II Camouflaged Linen Relic.

All blanks will come with one COA per blank.
COAs are 4" x 6" card stock with foil COA seal.

The RAF Gloster Gladiator Mk. II, a biplane fighter, was a symbol of Britain’s resilience during the early years of World War II. Entering service in 1937, it was the RAF’s last biplane fighter, powered by a Bristol Mercury VIII engine, delivering 840 horsepower. Despite its outdated design, the Gladiator excelled in agility, with a top speed of 257 mph and a distinctive fabric-covered frame. It saw action in the Battle of Norway, the Mediterranean, and the defense of Malta, where three Gladiators—nicknamed Faith, Hope, and Charity—famously held off Italian forces. Its rugged construction and twin Vickers machine guns made it a tenacious defender before being outclassed by modern monoplanes.

Our pen blanks incorporate a rare relic: a piece of camouflage linen from the aircraft’s skin, preserving the Gladiator’s wartime legacy. Each blank is crafted to honor this historic fighter, offering aviation enthusiasts, historians, and collectors a tangible connection to its storied past. Transform the spirit of the Gladiator into a unique writing instrument, celebrating its courage and endurance.

Relic Details: The camouflage linen, sourced from a Gloster Gladiator Mk. II, showcases the authentic fabric skin used in its construction, a testament to the craftsmanship of 1930s aviation technology.
