This one was apparently used on the cover of some Comics CD, but where the original drawing came from I've no idea. Nice position, though.
This looks like a typical modeling assignment of the kind Bettie did in the 50's. She's bending over just far enough to remind us that she possessed a nice, spankable bottom

I can't be sure this is Bettie, but without intending to be funny, it does look like her (I'd know that, er, face anywhere). This book was for sale recently, but they wanted about $71 (Canadian) for it. Not really a spankable position, but it sure is a spankable bottom, and nude shots of Bettie are not very common. To the best of my knowledge, except for her Playboy playmate pose, the only times that Bettie posed fully nude were for various camera clubs (as they were called). This would involve a bunch of guys standing in a semicircle taking photos of a nude model - not exactly the best conditions for excellent photography, and you have to believe the models were at least somewhat uncomfortable. But they needed the money, and of course the club could pool its resources to offer a reasonable(?) modeling fee - I'm just guessing, of course, as I have no idea what they paid. Jim Linderman of Vintage Sleaze has looked into this phenomenon more than I have.
I don't have an accurate count, but there certainly seem to have been more black & white photos of Bettie than color ones. I much prefer color to black & white for all photographic purposes, especially erotic ones, so as you may imagine I was pleased to find this one of Bettie bending over.
