Marvel Tales #21

In "The Man in the Crime-Master's Mask!", Thor answers a desperate call from Doctor Strange, whose life hangs in the balance after a brutal mystical assault. With Loki exploiting a rift between Thor and Odin to abduct Jane Foster, the God of Thunder must battle deception and dark magic on Earth—while a recovering Strange stands ready to aid in the final reckoning. Written by Stan Lee and brought to life by Jack Kirby’s dynamic art and Chic Stone’s inks, with lettering by Art Simek, this 1969 Marvel Tales gem features a cover by Steve Ditko, whose distinctive style captures the mystery and menace of the Crime-Master’s true identity.
