Superman #137

In "The Lady and the Lion," Clark Kent and Lois Lane find themselves stranded on a remote island, where Clark finally reveals his secret identity to Lois—and proposes. But when he realizes he can escape, he must convince her that his heroic acts were all staged to avoid the engagement. Written by Otto Binder and illustrated by Kurt Schaffenberger, with a cover by Curt Swan and Stan Kaye, this 1958 classic captures a rare moment of vulnerability and humor in Superman’s early adventures.
