They did not have children, neither kept regular office hours, and they had ample money. Geisel also felt that traveling helped his creativity. Geisel’s success with the Flit campaign led to more advertising work, including for other Standard Oil products like Essomarine boat fuel and Essolube Motor Oil and for other companies like the Ford Motor Company, NBC Radio Network, and Holly Sugar. His first foray into books, Boners, a collection of children’s sayings that he illustrated, was published by Viking Press in 1931. It topped The New York Times non-fiction bestseller list and led to a sequel, More Boners, published the same year. Encouraged by the books’ sales and positive critical reception, Geisel wrote and illustrated an ABC book featuring “very strange animals” that failed to interest publishers.
