Just a quick link over to a community that I discovered via Ursula Vernon's friends page: vintage_sex. It sounds odd at first, yes, but it's actually rather fascinating; its a great reference for sepia tones, period standards of beauty, costuming, & prudence, and- of course- the female nude. Very voluptuous and (Jason!) Art Nouveau, so it's really worth a looksee... Just as long as your parents aren't hawking over oyur shoulder, and you aren't at a school computer :)
Oh, and some of the shots are hiii-larious. Have fun!
