This Official Major League (Selig) baseball is signed on the sweet spot by the "Say Hey" kid himself, Willie Mays. Mays has also penned 15 statistical inscriptions on the ball, including "660 HR"; "MVP 54, 65"; "3,283 hits"; "ROY 51"; "H.O.F. 79" and "4 HR Games." Although some of the inscriptions show light bleeding, this is a tough collectible ball to come across. The ball features a "Say Hey" Authenticated hologram and an JSA authentication sticker.
