Doom Patrol #47

Grant Morrison, Richard Case, and Mark McKenna's run on Doom Patrol continued to push the boundaries of mainstream superhero comics in 1991, and this issue — titled "The World, the Flesh, and the Devil" — arrives with a memorably unsettling cover by Simon Bisley. That image speaks for itself: a grotesque, bandage-wrapped figure looms over a wide-eyed, disheveled man clutching a knife, while skulls and monstrous faces crowd the shadows around them. It's the kind of cover that earns the "Suggested for Mature Readers" label without a moment's hesitation.
