What could be better than a Near Mint 1951 Yankees ball with both Mantle and DiMaggio? How 'bout one that belonged to the team's Hall of Fame manager Casey Stengel? Here you go. 27 black fountain pen signatures on a bright William Harridge AL ball, with Joltin' Joe on the sweet spot, Mantle, Stengel, Berra, Rizzuto, Martin, Reynolds, Collins, Lopat, McDougald, Raschi, Bauer, Sain, Coleman, Woodling, Brown, Kuzava, Houk, Silvera, Morgan, Ostrowski, Hopp, Shea, Brideweser, Hogue, Overmire and Schallock all present. Autographs range from 7s to 9s overall, with most in the 8/10 range. In Stengel's hand surrounding Reach logo, and above DiMaggio on the sweet spot is proud inscription "1951 World Champs". "37" notation on ball as well, designating this highly coveted sphere as one of Casey's own stash. Wow.
