Trememdous set of Hall of Fame signatures. With the admission of former stars of the Negro Leagues into the National Baseball Hall of Fame in 1971, the value of a ball signed by Hall of Famers rose, because now the Hall represented great ball players of all races. The 1974 Hall of Fame Induction Class included New York Yankee greats Mickey Mantle and Whitey Ford, plus umpire Jocko Conlan and vintage player Sam Thompson. Signed baseball with 22 signatures: Mantle, Paige, Stengel, Ruffing, Medwick, Grove, George L. Kelly, Page, Rice, Feller, Gehringer, Lloyd Waner, Irvin, Ford, Lyons, Coveleski, Haddix, Musial (twice), Conlan, Buck Leonard, Cool Papa Bell, Terry. On National League Feeney ball. Signatures 7/10, condition EX-MT. PSA LOA.
