Before Crisis on Infinite Earths rebooted the Man of Steel, writer Alan Moore and longtime Superman artist Curt Swan decided to give the Silver Age version of the character a proper sendoff. Written as an homage to the wonky tales of the Mort Weisenger-era, this story pulled no punches and appealed to the more nostalgic sensibilities of comic book fans.

This title doesn’t follow a strict continuity, nor has it ever been referenced again, but as far as Moore was concerned, this was the last Superman story ever. Whatever Happened to the Man of Tomorrow? saw the death of Krypto, Lex Luthor, Lana Lang, Jimmy Olsen, and others. It’s a grandiose curtain call for Superman that was both emotional and adrenaline pounding.

Moore shows yet again just why he’s not simply the most important DC writer in history, but perhaps the most important comic book writer of all time.
