No NBA player loomed larger than Wilt Chamberlain, whose name still dominates the NBA record books. The legendary center inscribed this Spalding NBA indoor-outdoor full-sized Basketball in silver, adding his #13. The lot includes a photo of the Hall of Famer shaking hands at the signing. Chamberlain, while playing for Philadelphia, became the only player ever to score triple digits in a professional basketball game, torching the New York Knicks for an even 100 points on March 2, 1962 in a game played in Hershey, PA.
