Adventure Comics #33

Craig Flessel's cover for this December 1938 issue crackles with aerial tension — a black-clad figure clings desperately to the landing gear of a red-and-cream monoplane marked with a skull-and-crossbones emblem, dangling in mid-air as the craft streaks forward. The dizzying low angle and speed lines make you feel the rushing wind, and that ominous pirate insignia hints at the dangerous skies ahead. Inside, Fred Guardineer delivers 64 pages of thrills, including the sixth chapter of his "El Diablo" serial — pulse-pounding pulp adventure at a dime a copy.
