From 1976 to 2009, the renovated Yankee Stadium featured blue, hard-plastic seat backs such as this special one that features signatures and inscriptions from 27 Yankee greats such as Rivera, Jackson, Ford, Gooden, Strawberry, Berra, Winfield, O'Neill, Boggs, Guidry, Gossage, John, Mattingly, Nettles and more. Jim Leyritz noted that he hit the last home run of the 20th Century in Game 4 of the 1999 World Series against the Braves. Even team announcer Michael Kay got into the act, for whatever that's worth. The seat back measures 21.5x15.5" and is signed in 8/10 black Sharpie.
