This epic twig was used by the 17-year-old Gretzky during his one season in the World Hockey Association. It came from a member of the Oilers organization and purportedly was one of two he used during Game 6 of the 1979 Avco Cup Final against Winnipeg. As if it needed more collectible appeal, it’s the same model stick seen on his 1979-80 O-Pee-Chee Rookie Card.
