Before Dr. Seuss emerged as a famous children's book author, Theodore Suess Geisel was just like everybody else, with the exception he was always endowed with artistic talent. Prior to "The Lorax", "The Cat in the Hat", and "How The Grinch Stole Christmas!", Theodore spent his days illustrating advertisements for companies like Ford and NBC. DesignTaxi recently gathered a collection these rare Seuss illustrations that can be discovered in the thumbs above. Enjoy! [DesignTaxi]
