This accounting ledger from a game played on November 12, 1892 in Pittsburgh is the first documented proof that a player was paid to play football.  Note the line item that shows William "Pudge" Heffelfinger was paid $500 to play in the game.  Apparently, he was well worth it, as the Alleghany Athletic Club defeated the Pittsburgh Athletic Club, 4-0.  Heffelfinger recovered a fumble and returned it for a touchdown for the game's only score.  Touchdowns were worth just four points in 1892.

The ledger is among the most significant documents in the Pro Football Hall of Fame’s vast collection. It currently is on exhibit in Pittsburgh, Pa. as part of the Hall of Fame’s traveling exhibit, Gridiron Glory.
