I have a small collection of Otis Sweat's 'Mango Motel' gleaned from 'Cavalier' magazine - all are printed on the original brown paper stock. Your post is the first example I've seen on the internet. I wonder if they've been collected anywhere?.
Hi Warwick, finding Sweat's comic art he did for Cavalier is quite hard. I've been a fan for years and I've only come across half a dozen examples on the internet. All his other art is pretty easy to see through a google image search. I don't know of any dedicated collectors but you may get lucky if you dig around places and forums that have hardcore erotic art posters like Vintage Erotic Forum. Copyright issues mean I have to be careful what I post but I'll definitely post some more examples like this one if I come across them in the future.
Comments welcomed and appreciated. Thank you.
