Blackhawk #64

This May 1953 Quality Comics entry puts the whole Blackhawk squadron — their portrait heads ringing the top of the cover — up against a genuinely unsettling threat: "The Incredible Flying Submarines from the Underwater Kingdom of the Demon Massacar." Reed Crandall's cover art crackles with kinetic energy, depicting a sleek black-and-yellow hybrid craft taking a direct hit mid-air while enemy submarines burst from the churning sea below, as panicked enemy sailors scramble around a smoking multi-barreled gun emplacement in the foreground. For ten cents, this issue promises exactly the kind of imaginative, high-stakes adventure that made Blackhawk one of the standout action titles of its era.
