Geisel was able to draw few cartoons in The Saturday Morning Post. He signed his work "Dr. Theophrastus Seuss" then changed it to "Dr. Seuss". At the age of 23 Geisel got a job as a cartoonist for Judge Magazine in New York. Geisel's work included drawing cartoons and advertisements with his unusual, zany creatures. When Judge Magazine went out of business, Flit Household Spray hired Geisel to continue drawing their advertisements. Geisel also continued to sell cartoons and humorous articles to magazines. Sorry if this is too detailed, hope this helped!
