After working as a Disney animator, Walt Kelly struck out on his own and Pogo first appeared in a 1941 Dell comic. By the late 40's Kelly had transformed Pogo into a newspaper strip. The first of 45 books, simply titled Pogo, was released in 1951. This was quickly followed by I Go Pogo, Uncle Pogo's So-So Stories, The Pogo Papers, and The Pogo Stepmother Goose.
