In "Superboy Visits the 50th Century!", the Boy of Steel is pulled through time by a scientist's device and finds himself in the 50th Century, where his very existence is met with disbelief. Written by Robert Bernstein and illustrated by Ramona Fradon, this adventure blends time-travel intrigue with a touch of youthful wonder, as Superboy grapples with a future that has forgotten him. The cover by Curt Swan and Stan Kaye captures the moment with a striking, timeless image of the young hero in a far-flung world.
