Captain Marvel Jr. #7

This May 1943 Fawcett issue delivers a vivid cover by Mac Raboy, showing Captain Marvel Jr. in his blue-and-gold uniform riding atop a massive swordfish as it leaps through churning surf — cape streaming dramatically behind him. In the foreground, a young man sits at a desk writing, gazing up as though imagining the underwater adventure announced on the cover itself: "The City Under the Sea." Packed with 68 pages of full-color comics, this is a fine example of wartime Fawcett publishing at an energetic and imaginative peak.
