The Advertising Artwork of Dr. Seuss. The description above helps people like me that never heard about Dr. Seuss:
Before Theodore Seuss Geisel found fame as a children’s book author, the primary outlet for his creative efforts was magazines. His first steady job after he left Oxford was as a cartoonist for Judge, a New York City publication. In 1927 one of these cartoons opened the way to a more profitable career, as well as greater public exposure, as an advertising illustrator. This fortuitous cartoon depicts a medieval knight in his bed, facing a dragon who had invaded his room, and lamenting, “Darn it all, another dragon. And just after I’d sprayed the whole castle with Flit” (a well-known brand of bug spray).
