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 an 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).
