Well what do you know

I just found that I have a book entitled Erotic Art in my bookshelf. It was published in 1968 (or MCMLXVIII, as the book states). I've only leafed through it, but it appears to be the history of erotic art. It's got "41 Color Plates and 400 Black and White Plates."

The best part?

It belonged to my now-deceased paternal grandfather.
