Batman: The Long Halloween #7

Part seven of thirteen in Jeph Loeb and Tim Sale's celebrated limited series, this "April Fool's Day" chapter arrives with one of the most stylish covers in the run. Tim Sale's artwork places the Riddler front and center against a sharp yellow-green background — question-mark-covered suit, bowler hat, raised pistol, and question-mark cane in hand — captured mid-strut with a jaunty, almost theatrical confidence. It's a perfectly composed portrait that makes the Prince of Puzzles feel genuinely menacing and oddly charming all at once.
