From the cover of Wimmen's Comix #4 (1974; art by Shelby Sampson)
By 1970, the underground comix field had come into its own as a creators' alternative to Comics Code restrictions on language, art and subject matter. This freer, "anything goes" environment was a positive development for comic books overall (otherwise I wouldn't be making all these posts about it). But it also had a darker side: an increased emphasis on content that was brutally degrading to women, and the exclusion of women creators from the most popular comix titles.
