This book contains hundreds of sketches, including early color drawings from the master of underground comic art, cover roughs for the legendary Zap and Head comics, the original Keep On Truckin' sketches, the first appearance of Mr. Natural, plus his evolution and refinement, Fritz The Cat, the Old Pooperoo, and many, many voluptuous Crumb girls, all wrapped up in a quality hardcover featuring an illustration newly hand-colored by Crumb himself.
