Picked up this ticket stub today. It is from the major league debut of Masanori Murasaki, the first Japanese born player to appear in a major league game. He pitched an inning in relief for the SF Giants in a loss to the NY Mets on 9/1/64. He would finish out the '64 season with the Giants and appear in 45 games the next season before returning to Japan for the remainder of his career. It would be another 30 years before a player from Japan played in the major leagues again when Hideo Nomo pitched for the Dodgers.
Here's a nice piece about Murasaki:
