Underground Comix refers to a genre of comic books that emerged in the 1960s and 1970s, characterized by their countercultural themes and alternative art styles. These comics often tackled taboo subjects such as politics, sexuality, and drug use, reflecting the social upheaval of the time. They were typically self-published or distributed through independent channels, bypassing mainstream comic book publishers. Key figures in the Underground Comix movement include artists like Robert Crumb and Art Spiegelman, who used their work to challenge societal norms and express personal experiences. The movement played a significant role in the evolution of comics, paving the way for more diverse and experimental storytelling in the medium.
