The defining moment of the 1932 World Series was unquestionably Babe Ruth's "Called Shot," his last home run in postseason play. The historic blast was recorded in Game 3 and the Yankees closed out the series with a sweep in Game 4, both played at Wrigley Field in Chicago. The ball on offer here is a ONL (Heydler) sphere signed by all four umpires (Klem, Dineem, Van Graflan, and Magerkuth) who worked the series, plus John McGraw who attended the games. As such, there is a fifty percent chance that this ball was signed at the "Called Shot" game at Wrigley. The ball was treated with a light coat of shellac to protect the autographs, which are all legible to some degree, although some are more legible than others. Historic to say the least.
