Hardin Penworks, LLC, certifies that material supplied to the artisan of the accompanying hand-crafted item was sourced from the wooden panel of a section padded wall of Shea Stadium from along the third base line.
Formally known as William A. Shea Municipal Stadium, it was a stadium in Flushing Meadows-Corona Park, Queens, New York City, NY. Built as a multi-purpose stadium, it was the home park of MLB's New York Mets for 45 seasons from 1964 to 2008, as well as the NFL's New York Jets football team from 1964 to 1983.
The venue was named in honor of William A. Shea, the man who was most responsible for bringing National League baseball back to New York after the Dodgers and Giants left for California in 1957. Shea always used a natural grass surface, in contrast to other multi-purpose stadiums of the same era. Shea Stadium's final game was September 28, 2008.

Giants Stadium: Jets' Meadowlands Monument of Gridiron Greatness
Giants Stadium towered over the New Jersey Turnpike in East Rutherford, a concrete colossus shared by the New York Jets and Giants since its groundbreaking genesis. Conceived in the early 1970s to replace the creaky Yankee Stadium and Polo Grounds, the $78 million marvel—funded by New Jersey Sports and Exposition Authority bonds—broke ground in 1972 and roared open on October 10, 1976, with the Giants edging the Dallas Cowboys 14-10 before 76,042 fans—heralding a new era of Meadowlands might and instantly etching its dual-sport destiny into NFL lore, with the Jets joining as tenants in 1984 after Shea Stadium's shade.
Ballooning from 76,891 seats to a raucous 78,741 capacity on AstroTurf (swapped to grass in 2003), Giants Stadium encircled a standard 120x53-yard battlefield—fostering fender-banging frenzy with those iconic upper decks and end-zone scoreboards. Facelifts flared: 1984's $10 million lighting upgrades, 1994's $30 million club seating surge, 2000s' $100 million video board and suite expansions—blending raw, rattling intimacy with fan-favorite fury, all while the Jets and Giants cohabited until MetLife's 2010 call.
Jets' jetstream ground for 26 seasons, the stadium cradled Super Bowl III's upset (1969 pre-park echoes in 1986's AFC Championship thriller), Namath's guarantees, Sack Exchange supremacy (1980s), and Mark Gastineau's records amid 300+ home wins. Record roars hit 79,310 for 1981's playoff pulse vs. Bills, pulsing with "J-E-T-S" chants and tailgate traditions. Demolished in 2010 for parking paradise, Giants Stadium endures as a Meadowlands testament to tenacity, triumphs, and timeless Jet green in NFL's northeast.

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.
