Comic Images' 1991 Incredible Hulk set captured fan interest during a period when comic card collecting was experiencing significant growth. The early '90s saw publishers beyond traditional sports card makers entering the trading card market, bringing comic book properties to collectors in card form. These sets became part of the foundation of modern non-sports card collecting. "I'm Grey" represents one of the character-focused cards from the set, exploring the Hulk mythology through individual cards. Collectors appreciate these character study cards for their artwork and their role in documenting how the Hulk was visually interpreted during this era of comic card production.
