Action Comics #510

The cover of Action Comics #510 sets up a genuinely compelling moral dilemma: Superman stands firm as a desperate Lex Luthor — blasted by energy fire and collared by a thug — pleads "Superman, help me! You've sworn to save ALL life—" while the Man of Steel coldly replies "Except yours—Luthor!" Two armed gunmen close in from either side, making the scene crackle with tension. Ross Andru and Dick Giordano bring real punch to the composition, and the banner teasing "Luthor's Last Stand!" promises that Cary Bates and Curt Swan have cooked up something that pushes Superman's code of ethics right to the edge.
