Action Comics #499

In "As the World Turns... For the Last Time!", Superman faces a crisis unlike any before—Earth itself is on the brink, and the entire planet believes it's doomed. With help from the alien Vartox, who's more distracted by Lana Lang than he lets on, Superman races to uncover the truth behind the global panic. Written by Cary Bates and brought to life with Curt Swan’s iconic art, this 1979 classic sees the Man of Steel confront a threat that could end everything—while Vartox must decide whether to stay and fight, or seek a new world in need. The cover by Ross Andru and Dick Giordano captures the moment’s weight in bold, dramatic strokes.
