Steve Clay Wilson (born July 25, 1941), better known as S. Clay Wilson, is an American underground cartoonist and central figure in the underground comix movement.
 Wilson attracted attention from readers with aggressively violent and sexually explicit panoramas of lowlife denizens, often depicting the wild escapades of pirates and bikers.
 He was an early contributor to "Zap Comix", and Wilson's artistic audacity has been cited by Robert Crumb as a liberating source of inspiration for Crumb's own work.
 Recalling he first saw Wilson's work (in about 1968) Robert Crumb said, "The content was something like I'd never seen before, anywhere, the level of mayhem, violence, dismemberment, naked women, loose body parts, huge, obscene sex organs, a nightmare vision of hell-on-earth never so graphically illustrated before in the history of art... Suddenly my own work seemed insipid..."
Introducing Kafka, also known as R. Crumb's Kafka, is an illustrated biography of Franz Kafka by David Zane Mairowitz and Robert Crumb.

 The book also details Kafka's biography in a format that is part illustrated essay, part sequential comic panels.
 The book was released as part of the "Introducing..." series by Totem Books; the popularity of Crumb's renditions of Kafka's works led to additional printings under the title "R. Crumb's Kafka",and its most recent edition by Fantagraphics Books (2007) is simply titled "Kafka".

George Joseph Herriman (August 22, 1880 – April 25, 1944) was an American cartoonist best known for the comic strip "Krazy Kat" (1913–1944).
 More influential than popular, "Krazy Kat" had an appreciative audience among those in the arts.

The Comics Journal" placed the strip first on its list of the greatest comics of the 20th century.
 Herriman's work has been a primary influence on cartoonists such as Will Eisner, Charles M. Schulz, Robert Crumb, Art Spiegelman, Bill Watterson, and Chris Ware.
Keep on Truckin&apos; is a one-page comic by Robert Crumb.

 The strip's drawings became iconic images of optimism during the hippie era.
