The Sensational She-Hulk #37

Even the cover of The Sensational She-Hulk #37 (March 1992) is in on the joke: Wolverine, the Punisher, and Spider-Man charge across the front in an action-packed blaze of gunfire and smoke, while a speech balloon from She-Hulk herself cheekily notes that nothing is actually said about them being in this issue. John Byrne both writes and illustrates the book, and his cover perfectly captures the series' trademark blend of Marvel muscle and self-aware humor. If you've ever wanted a comic that winks at its own marketing while still delivering a genuinely fun cover image, this is a fine place to start.
