Superman #175

That snarling, rock-hewn face filling the entire cover belongs to a Jokerized Doomsday — glowing red eyes, jagged stone teeth bared in a deranged grin — and it's one of the most unsettling images DC put on a spinner rack in 2001. This issue ties into the Joker: Last Laugh crossover event, and the "Doomsday Rex" story title promises that Superman's most physically devastating nemesis has been twisted into something even more unpredictable. Ed McGuinness's cover pencils and Liquid!'s inks deliver a portrait so up-close and menacing it practically leaps off the page — a perfect encapsulation of the Loeb-McGuinness run at full throttle.
