HULK SMASH! 56 years ago this month a gray Hulk debuted in his own book, The Incredible Hulk #1. (Due to a shading inconsistency in printing the first issue, Hulk became his now-iconic green in The Incredible Hulk #2.) Among Stan’s influences in creating the character were Frankenstein and Dr. Jekyll and Mr. Hyde. #hulk #hulksmash
