Strange Tales #110 (July 1963)

A key issue whose cover hides its key. Kirby's art sells the lead Human Torch story, with Johnny trapped in a mirror prison by the Wizard and Paste-Pot Pete. Doctor Strange made his debut inside, in a short Steve Ditko back-up that gets no mention on the cover at all. Collectors pay for the sorcerer; what they get on the front is the Torch.
