Haha, my mom is awesome. She sent me a link to scans of Chinese "pornographic" books for art reference.

(They're just artistic nude photos, really. Some of them very lovely, and hardly even "centerfold" material.)

I would like to have the book set itself, but it costs 5120 Yuan. Which is like... ::googles:: $618. Easier to find porn on the net, I suppose. (I kid! I kid!)

Edit: OMG, now she's offering to buy it since it's only ~$35 online XD
