1956 New York Yankees Team Signed Baseball. 

Don Larsen's perfect game. Mickey Mantle's Triple Crown. Another World Series victory over the Brooklyn Dodgers. It was quite a year in the Bronx, and here we present a solid team signed relic from that historic squad, a OAL (Harridge) sphere autographed by twenty-five pinstriped champs. Signatures remain 7/10 to 9/10 on average and include: Sturdivant, Silvera, Kucks, Ford, Coleman, Byrne, Grim, Morgan, Bauer, Howard, Siebern, Martin, McDermott (only year with team), Mantle (clubhouse), Berra, Carey, Wilson, McDougald, Larsen, Cerv, Hunter, Carroll and three more. Full LOA from PSA/DNA.
