Master Comics #72

This September 1946 Fawcett anthology puts Captain Marvel Jr. front and center, his blue-and-yellow-caped figure diving fist-first into a bespectacled villain who's being blasted apart in a burst of explosive light — all while giant, screaming "EEEE" sound-effect letters fill the air around them, making the whistle's chaos almost audible off the page. The cover story, "The Whistle That Wouldn't Stop," promises exactly the kind of relentless, ear-splitting mischief that visual suggests. Rounding out the lineup are Radar, Nyoka, and Bulletman, making this a genuinely packed ten-cent package from one of Fawcett's reliable anthology titles.
