The Sensational She-Hulk #46

The cover of this 1992 Marvel issue says it all with a single striking image: She-Hulk's green face and her human alter ego Jennifer Walters' pink-skinned face are literally interlocked as jigsaw puzzle pieces, two identities mid-scramble and wide-eyed in shared surprise. It's a wonderfully clever visual concept that perfectly suits a series always willing to play with its own premise. John Byrne — handling writing, art, inking, and lettering — delivers a cover as witty as the story title "Oops!" promises.
