Unique Casey Stengel 1956 Yankees Single Signed OAL Harridge Baseball. Presented here is quite possibly the finest Casey Stengel ball in the entire hobby!  Aside from it's pristine condition, The Ol' Professor signed this ball with the unique inscription "The best from the 1956 Yankees and Casey Stengel".  The 1956 season was arguably Casey's finest as skipper, the Yankees defeated the Dodgers to win their 17th World Championship and Mickey Mantle won his only Triple Crown award.  This is more than just a Casey Stengel ball, it is a Casey Stengel ball signed on behalf of the entire 1956 Yankees, and everything that comes along with that.  It is the definition of a good luck charm.  And it comes from a man who was famous for predicting his team's fortunes.  Hopefully the future owner of this ball will have as much luck as Casey did in 1956.  Includes Full LOA from PSA.  (Photograph of Casey Stengel NOT included)
