USA Basketball logo Spalding regulation size rubber basketball autographed beautifully in thick silver paint by UCLA Bruins legends and NBA Hall of Famers Kareem Abdul-Jabbar and Bill Walton. Both autographs obtained in person. Kareem is a notoriously reluctant signer. With certificate of authenticity from AutographsForSale.com. NOTE: due to the age of the basketball, it may not stay fully inflated.
