After retiring 27 consecutive batters on September 9, 1965, Koufax became the sixth pitcher of the modern era and eighth overall to pitch a perfect game. This perfect game was also Koufax's fourth no-hitter, breaking Bob Feller's Major League record. From that memorable day comes this beautifully signed ticket stub. Encapsulated by PSA, the signature has been graded 10/10 with the stub being Authentic. Ticket itself has a nice appearance but for clipped bottom left corner.
