Two very different men, from different leagues and different countries. Yet Roberto Clemente and Thurman Munson had much in common. But what many don't realize is that were also teammates, on the 1969 San Juan Senadores of the Puerto Rican Winter League. Offered is what quite possibly could be the only ball still known to exist with both Clemente (sweet spot) and Munson's signatures. The other key signature is Willie Crawford who played with the Dodgers. Official league baseball is "Liga Profesional de Puerto Rico." Beautiful signatures are an average EX-MT. The ball is shellacked and slightly browning from age. A total of 26 signatures are found on the ball.
