Challengers of the Unknown Ad
April 1958

Copy: ???
Art: Jack Kirby
Text and art © DC Comics

Synopsis: An ad announces the Challengers in their own magazine.

This ad ran in various DC comics, including Adventure 247 with its first appearance of the Legion of Super-Heroes.

The copy is rousing and fun. "Men of reckless courage... Danger grimly coiled... Death means nothing to these heroic adventurers... dedicated to a second life!"

Nice to see the boys got off with a bang, even if they did spell Prof's last name "Hale."
