Captain Marvel Adventures #70

From Fawcett's self-proclaimed highest-circulation comic magazine comes this March 1947 entry in the World's Mightiest Mortal's long-running series — and the cover promises something genuinely unsettling. Captain Marvel, in his familiar red-and-gold costume, stares wide-eyed at an ominous grey box bearing a question mark and a sinister face, as the bold banner below confirms: "Captain Marvel and the Horror in the Box." C. C. Beck's cover art captures that perfect blend of superhero bravado and creepy mystery that made these Fawcett adventures so irresistible, and with Bill Woolfolk writing and Pete Costanza on interior art, issue #70 is a fine snapshot of the era's imaginative storytelling at its peak.
