Official National League Giles Baseball signed by 11 members of the 500 Homerun Club including Mickey Mantle, Ted Williams, Eddie Mathews, Willie Mays, Mike Schmidt, Harmon Killebrew, Willie McCovey, Hank Aaron, Reggie Jackson, Ernie Banks and Frank Robinson. A couple of minor ink smudges on the ball under the Williams signature, otherwise the ball is nice and clean. NM/Mint
