Cert #SR036282 if you search the cert number on CAS site it will show the Mantle as Clubhouse, William Harridge ball, nearly all signatures are in dark blue ballpoint, ball has minor toning. Despite the clubhouse Mantle this is still a loaded ball with the very tough Elston Howard autograph along with HOF'ers Whitey Ford, Yogi Berra and Enos Slaughter, and popular players Moose Skowron, Hank Bauer, Ryne Duren, Bobby Richardson, Tony Kubek and more.
