Superman's Pal, Jimmy Olsen #20
In "Jimmy Olsen's Super-Pet," Jimmy's latest adventure takes a whimsical turn when he swears he's met a mermaid and gained a magic ring granting underwater breath—only to learn the truth behind the tale is far more clever than he imagined. Written by Otto Binder and brought to life with Curt Swan’s crisp art and Ray Burnley’s inks, this 1957 classic captures Jimmy’s boundless curiosity and Superman’s playful interference. The cover by Curt Swan and Stan Kaye perfectly captures the issue’s lighthearted mystery.
