Mike Bossy's four-goal performance during his historic 50-goals-in-50-games campaign is the centerpiece of this January 13, 1981 ticket stub from Nassau Coliseum. The PSA label identifies the New York Islanders' 6–3 victory over the Pittsburgh Penguins and credits Bossy with season goals 42–45. This was a major step toward his achievement, rather than the game in which he scored his 50th goal. Encapsulated by PSA as a ticket stub with a numerical grade of 4.
