The 1991-92 Upper Deck Dikembe Mutombo #446 is a vintage base basketball card manufactured by Upper Deck that showcases the Hall of Fame center rising high above a defender to secure a powerful dunk. Designed with a clean, asymmetric layout popular in early-90s premium sports cards, the front image features a borderless action shot bordered by a solid yellow right-hand sidebar stamped with bold blue "NUGGETS" lettering.
