Of the 23 Perfect Games thrown in Major League history between 1880 and 2023, Don Larsen's outing in Game 5 of the 1956 World Series remains the only postseason version to this day. This Yankee Stadium Bleacher Admission ticket stub is from that October 8 effort, with the Yankees claiming a 2-0 victory. Sent to PSA by Lelands where it was encapsulated and graded VG 3 MK w/AUTO 10, this fine World Series memento even has a hand written "Oct 8 - 1956 - Larsen Perfect Game" and "97 Pitches" presumably written by the ticket's original owner.
