Rex Dexter of Mars #1

"Captured By Lord Marvel" kicks off in the 1940 Fox comic Rex Dexter of Mars #1, a standout early sci-fi adventure from Dick Briefer, who wrote, drew, and inked the entire issue. When a mysterious meteor strikes Asia, leaving behind a growing, featureless wasteland known as "The Bald Spot," scientists are baffled—until they uncover a bizarre, jellyfish-like life form thriving in the zone. Rex Dexter, the series' intrepid hero, takes on the threat with a bold plan to stop the invaders before they spread further. The cover, also by Briefer, captures the eerie tension of the alien threat with sharp, dynamic lines.
