Well, I've seen a few slave market pieces, but they're not something I had considered. They were basically nude or stripped to the waist standing next to the seller - usually some large sweaty guy... There's no tease and all you're painting are basic fleshtones. I thought maybe a harem with the wives/concubines laying about on couches, pillows, a sunken bath, etc, along with some potted palms and other background pieces might look nice. They're as close as I can get to the traditional pinup types that I like. I'm sure it's out there, but I don't recall seeing any. I did find some porn pieces, but I have no interest in those...
Salud,
