Journey into Mystery #95
In "The Demon Duplicators!", a mad scientist's sinister machine turns Thor into a double, testing the limits of power and identity—only to reveal that even perfect copies can't replicate magic. Written by Stan Lee and R. Berns, with art by Joe Sinnott and colors by Stan Goldberg, this 1963 classic features a thrilling twist when the villain’s own duplication leads to an unexpected redemption. The cover by Jack Kirby and Dick Ayers captures the chaos in bold, dynamic lines.
