In "I Discovered Gorgilla! The Monster of Midnight Mountain!", Stan Lee and Larry Lieber team up with Jack Kirby’s dynamic art and Steve Ditko’s sharp inks to deliver a classic Marvel sci-fi thriller. When a gaseous alien criminal named Kragoom plots to possess the mind of Earth’s first astronaut, the fate of the planet hangs in the balance—just as the skies above Midnight Mountain begin to stir. The cover, penciled by Kirby and inked by Ayers, captures the eerie anticipation of an alien arrival.
