Roger Bradfield
THERE'S AN ELEPHANT IN THE BATHTUB published in 1964, was the first children's book by Roger Bradfield. Check out the cover gallery on his web site to see more of his many titles. One of these books, PICKLE CHIFFON PIE, has been reprinted by Purple House Press with THE FLYING HOCKEY STICK to come this spring. I've got some more scans here and at The Retro Kid flickr group.
