I just picked this baseball up. This ball was the final pitch of a game between the Indians and the A's on June 15th, 1926. Rube Walberg had just won his 15th major league game by tossing a 5 hit shutout. I'm hopeful I can do some research and find out who made the last out. Would be great if this beauty got Tris Speaker to pop out. Rube wrote out the box score and starting pitchers and catchers for each team, so technically it is also autographed.
