Captain Marvel Adventures #89

Captain Marvel Adventures #89 brings Fawcett's red-suited champion face to face with the villainous Dr. Sivana, and C. C. Beck's cover captures the confrontation vividly — Captain Marvel tears apart a massive tangle of electrical machinery with his bare hands while a furious, bespectacled Sivana is pinned helplessly beneath the wreckage. The cover promises that Sivana's "Silent Sound Machine" is about to meet its match, making this October 1948 issue a satisfying showcase of the World's Mightiest Mortal at his most unstoppable.
