There have only been 13 Triple Crown winners in baseball history (batting average, home runs, RBI) and two of that elite club - Hall of Famers Mickey Mantle and Ted Williams - signed this ball and photo. Both have been authenticated by Upper Deck, with the photo being NRMT with hologram and 9/10 signatures in blue Sharpie. The ball - a NRMT American League (Bobby Brown) model - comes with the certificate, hologram and 8/10 signatures, also in blue Sharpie. Mickey Mantle earned his crown in 1956, while Ted Williams is one of only two men to have turned the trick twice (Rogers Hornsby was the other), in 1942 and 1947.
