Three great Red Sox Hall of Famers signatures on one baseball. Jimmie Foxx, Lefty Grove, and Joe Cronin signed Official American League Harridge baseball. Beautiful 8/10 Foxx, the slugger who hit 534 home runs, on sweet spot. Lefty Grove, who won 300 games and Cronin, the .301 lifetime hitter who became a noted manager, is 9/10. Light coat of shellac. Sources from family of long-time former Red Sox owner Tom Yawkey. PSA LOA.
