I think I was a bit too old for his kid books, but I’ll never forget that in a used bookstore (in Bozeman, MT?) I ran across a collection of his erotic drawings from a French publisher. I thought “Humph! Yeah, sure.” But when I checked it out –YOWSAH! They were vivid, inventive wildies with a heavy S&M component. I remember I had to hide it away in my bedroom in my parents’ house, but boy, was it a find, a revelation. I was saddened, but not surprised, that it almost ruined his career when the kid-book publishers found out about his porny works. Deserves a major revaluation.
