Action Comics #660

A Grim Reaper looming over a visibly weakened Lex Luthor — clutching a Superman emblem in one skeletal hand and raising a scythe with the other — makes for one of the most arresting covers DC published in December 1990, with Kerry Gammill and Brett Breeding delivering every ounce of dread the title "The Death of Luthor!" promises. In the background, a small inset of Superman stands watch, a quiet contrast to the grim tableau unfolding below. Roger Stern and Bob McLeod bring their story "Certain Death" to life inside, and this cover sets the stakes with striking confidence.
