Kim Deitch

On Wikipedia :

"Kim Deitch (born 1944) is an American comics artist. He was an important figure in the underground comix movement of the 1960s, regularly contributing comical, psychedelia-tinged comic strips (featuring the flower child "Sunshine Girl" and "The India Rubber Man") to New York City's premier underground newspaper, The East Village Other, beginning in 1967. He became editor of EVO's all-comics spin-off, Gothic Blimp Works, in 1969. He is also an important figure in the current alternative comics movement which evolved from the underground comix movement."

I've discovered his work with his comic "Boulevard of Broken Dreams" ("Une tragédie americaine" in french), one of my favorites graphic novels. Deitch chronicles the history of the animation industry through the eyes of an animator who is plagued by hallucinations of a demonic blue cat named Waldo.
