Also during this period, Crumb began to experiment with drugs, resulting in some bad experiences with LSD, but these "bad trips" only led to Robert creating some of his most enduring characters, including the pop icon< "Mr.Natural". During this time he was doing illustrations and strips for New York's "East Village Other", a Greenwich Village newspaper.

In 1970 Crumb sold the film rights to Fritz the Cat to film animator Ralph Bakshi and was released as an X-rated film to international acclaim, and another Fritz movie was made, but Crumb is known to have voiced his displeasure with both films, and disowns them.

Also in the early seventies, Crumb along with several friends (including Terry Zwiggoff, the producer/director of the recent film on Crumb's life) founded a jazz band and called it "the Cheap Suit Serenaders".

Unfortunately the seventies were also some of the most difficult times for Crumb. In Zap #1 which was published in 1968, Crumb created a six panel cartoon which ended with a big-footed character with his foot out saying "Keep On Truckin'". This had become a popular image of the hippie counter-culture and Crumb collected royalties for years, but a suit emerged challenging Crumb's copyright which hads never been registered and in 1977 a federal judge ruled that Crumb had let the image fall into the public domain, freeing pirates from any further royalty payments to Crumb.

Then he was smacked with an I.R.S. tax bill for $30,000. (some have said his accountant and his wife....), he divorced his wife Dana, and was forced to move to Paris, France until he could pay his tax bill.

Then in 1978 he met and married Aline Kominsky, a cartoonist with whom he created "Weirdo" magazine, and moved back to California.

In the middle eighties Robert's career took a turn when he became recognized as an international cult hero, drawing appearances in Newsweek, People and other magazines, and appearing on BBC-TV. His work was featured in the New York City art gallery "Psycadelic Solution" and in 1990 the Museum of Modern Art, in New York City, included his work in an exhibit called "High and Low" which also featured work by other cartoonists, including George Herriman.

Becoming disillusioned with living in the US, Crumb moved permanently to France in the late eighties where he lives happily ever after in a home he bought with six notebooks filled with his work.

Robert Crumb has become an icon of popular culture since breaking onto the scene with Zap #0. His crude "bigfoot" style, influenced by Kurtzman, George Herriman, E.C. Segar, Cliff Sterrett, Bud Fisher and comic great Basil Wolverton, infused with overt sexual release in contrast with his own self-repression have in them an insightful view of the American psyche of the late fifties anbd early sixties era. Crumb is one of those partially responsible for the lifting of previously unchallenged theorum of the "Father Knows Best" era.

Throughout the decades since, he has been hailed as an anachronist and an anarchist, a genius and a revolutionary. He is one of the best.
