The ones you found as a kid.
A far better a sex education than National Geographic.
There's an entire site called Bilkoscans that has some very high-quality scans of some outstanding pictures, obviously done with care and class.
I've seen the site's work crop up in quite a few places on the web. As of this writing it seems to be gone. It would be a shame if it were gone for good. Check the link occasionally, and see what comes up.
Update: It's been updated, upgraded and placed back on-line as of
October 30, 2006. Enjoy!
