Superman #168 2001

This 1964 "all-Luthor" issue features two tales. In "Luthor, Super-Hero!", Superman journeys to Lexor, where Lex Luthor is revered as a hero and Superman is powerless. Luthor's love interest is officially named Ardora here. The second story, "Lex Luthor, Daily Planet Editor!", sees Luthor challenging Superman in an unexpected role. This Silver Age classic is notable for its extensive focus on Luthor and includes a John F. Kennedy memorial on the letters page.
