Superman: From Krypton to Metropolis Comic
One of a series of four Justice League of America storybook/audio cassette sets which were written exclusively for Fisher-Price by DC Comics and published in 1982. The other three stories involved Batman & Robin, Wonder Woman, and the Justice League as a whole.
The 45-minute read-only cassette tape was stored in a flexible plastic sleeve on the back of the hardcover book. The story was read verbatim by actors in the style of 1940s radio shows.
