For those whose childhood didn't include this iconic image: Coppertone was a sunscreen product, the advertisements for which showed a drawing of a very young (under 10 years old) girl whose swimsuit bottom (as I recall, she wore nothing on top) was being pulled down by a cocker spaniel to reveal the contrast between her well-tanned back and very pale bottom.
Was the spaniel equipped with a large dildo?
