Before writing the best children’s books, Mr. Theodor Seuss Geisel was an ad man for 17 years. It all started when an ad executive’s wife noticed his cartoons in Judge magazine. Besides helping his family get through the great depression and helping him fund his early writing career, his work was notable because, as you can see above and below, it was freaking awesome. “Dr. Seuss: Ad Man” has a nice ring to it. A perfect prequel to Mad Men, whenever that ends. And I know just the guy to play this whimsical advertising illustrator.
