Probably you heard about Milo Manara, the great cartoonist that design beautiful women. On his website there is images for some new works, of old histories, of his kama sutra, images from your desktop or screensaver and you can buy exclusive works of his portfolio. For those who like videos, on Terra Erotica there are short animations, links, more images and other stuff. But, if you are looking just for beautiful girls, The Pin-up Files is the best link. All kind of pin-ups from different artists, links and a shop.

And for the end there is AMEA - World Museum of Erotic Art, with some artists, postcards, a session called "picture of the day", and the "current exhibit" with Félicien Rops. BTW, NSFW. Have fun.
