Famed dousing of Bill Parcells with Gatorade by Harry Carson (in the yellow security jacket) right before the end of Super Bowl XXI. Giants won 39-20 over the Denver Broncos, the first NFL championship for the New York Giants since 1956. The Giants started dumping Gatorade over players and coaches near the end of games during the 1985 season, but the practice started to really catch on in 1986. The highly watched telecast of this XXI Super Bowl was one of the first times that the "Gatorade shower" celebration received widespread national attention. 40+ signatures. Signed in silver felt tip marker. Notable signers: Lawrence Taylor, Harry Carson, Mark Bavaro, Phil Simms, Carl Banks, Leonard Marshall and Jim Burt (originator of the Gatorade shower).
