Comix Book is an underground comic book series published from 1974 to 1976, originally by Marvel Comics. It was the first comic of this type to be published by a mainstream publisher. Edited by Denis Kitchen, Comix Book featured work by such underground luminaries as Justin Green, Kim Deitch, Trina Robbins, Art Spiegelman, and S. Clay Wilson. While it did not depict the explicit content that was often featured in underground comix, it was more socially relevant than anything Marvel had previously published.
