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.

[1] In 1973, Marvel publisher Stan Lee became attracted to the energy and cutting-edge art styles of the underground comix movement (which, ironically, by this period was already beginning to wane).

As with the Curtis publications, the format allowed Marvel to dispense with the restrictions of the Comics Code Authority, thereby creating a freer creative space more akin to the no-holds-barred ethos of the underground.

Kitchen was also able to win a number of unprecedented concessions for his contributors, including the return of all artwork, and eventually allowing artists to keep their copyrights.

In addition to comics, issues of Comix Book usually featured text pieces like Kitchen editorials, interviews, and a letters page.
