Wholesale Postcard. Mr. Natural Whistling. Artist: R. Crumb

Robert Crumb (born August 30, 1943) — known as R. Crumb — is an American artist and illustrator recognized for the distinctive style of his drawings and his critical, satirical, subversive view of the American mainstream. He currently lives in Southern France. Though one of the most celebrated of comic book artists, Crumb's entire career has unfolded outside the mainstream comic book publishing industry. One of his most recognized works is the "Keep on Truckin'" comic, which became a widely distributed fixture of pop culture in the 1970s. Others are the characters Devil Girl, Fritz the Cat, and Mr. Natural. Mr. Natural: Long-bearded earthy worldly wise simple genius invented by cartoonist R. Crumb. The only man in history (according to one cartoon) to get a new lease on life when, once he had died, God asked him what he thought of Paradise and his scrupulously honest aesthetic appraisal of the whole place pissed off the Big Man big time.
