Marvel Mystery Comics is an American comic book series published during the 1930s–1940s period known to fans and historians as the Golden Age of Comic Books. It was the first publication of Marvel Comics' predecessor, Timely Comics, a division of Timely Publications.

Paul Gustavson was a Finnish-American comic-book writer and artist. His most notable creations during the Golden Age of Comic Books were The Human Bomb for Quality Comics, and the Angel, who debuted in Marvel Comics #1, the first publication of Marvel Comics forerunner Timely Comics. The Angel would star in more than 100 stories in the 1940s. The Human Bomb would later be acquired by DC Comics and make sporadic appearances as late as 2005.
