After leaving Oxford and returning to the United States, Ted needed to earn a living before he could think of marrying fellow Oxford student, Helen. He decided that he could make a living as a cartoonist, and was thrilled when one of his submissions was published in The Saturday Evening Post. His work caught the eye of the editor for Judge, a New York weekly, and Ted was offered a staff position. Many of the characters from these sketches resemble the more-familiar characters of his books: Horton-esque elephants, turtles that look like Yertle, Nizzard-like birds, etc.

Standard Oil recognized Ted’s talent—or at the very least, his obsession with Flit, the pesticide Standard was manufacturing at the time—and offered him a job in their advertising department. Flit’s competitor, Fly-Tox, offered Ted a similar contract and in true Ted Geisel form, he flipped a coin to make the decision. As a result, the phrase “Quick, Henry, the Flit!” was introduced into the American vernacular (Morgan, p. 65). In all, Ted spent over 15 years in advertising, primarily with Standard.

" The Manly Art of Self-Defense" is clearly one of Dr. Seuss's appropriately satiric works in the vein of "I'd Love to go to the Party, but I'm Absolutely Dead." The wonderfully erudite expression on the boy's face suggests that there is an aristocratic air to the "manly art of self-defense." But the cat's look of surprise implies that the boy does not grasp the reality of boxing. The cat, as is often the case in Ted's work, knows best.
