Single signed by the ultimate baseball Communist Fidel Castro. Castro balls are as difficult to find as he is. This is the first specimen we have had in years and the last one brought five figures. Signed in blue sharpie, baseball itself is a Japanese Mizuno. Interesting that the ball is from a neutral country rather than being American manufacture. Signature is 100% stable and will stay that way as long as you protect him. No, we do not have a Raul Castro ball waiting in succession.
