Official American League (Harridge) ball practically glowing with sporting fame. Hailing from the New York’s 1951 Championship win, this ball has an amazing lineup of twenty seven Yankee signatures. Joe DiMaggio across the sweet spot. Mickey Mantle from his rookie year, Yogi Berra, Billy Martin and all the rest. As this was manager Casey Stengel’s personal ball, his signature and “#37” is scrawled over the logo with the notation “1951 World Champions.” The signatures on this red stitched ball range from 7-9/10.
