 Following his third "Skippy" prose-fiction book, the essay collection "Skippy Rambles", Crosby began using his writing as primarily a vehicle for his beliefs.His 1931 memoir "A Cartoonist's Philosophy" was found to be too polemical for eight publishers, and Crosby published it himself, in a money-losing venture; his future books were all privately published under his own name or Freedom Press, which he founded in 1936.
