Spectacular 1960 World Series Pittsburgh Pirates official program signed in the cover by Hall of Famer and World Series hero Bill Mazeroski. Mazeroski of course hit the home run to win the World Series and defeat the dominant Yankees perhaps the most famous (or infamous depending on your sports allegiances) home run in the history of the postseason. In outstanding condition with light wear but bright clean graphics Mazeroski's signature in black Sharpie contrasts remarkably against the gold background. Basic cert from james Spence Authentication.
