Presented in Bibliotheca Universalis edition, The Big Butt Book explores the timeless appeal of the female buttocks - from small and snappy to bulky and sumptuous - based on the fourth art installation in the acclaimed body series by Dian Hanson. The numerous photographs, including shots of famous artists, range from 1900 to the present day, and are contextualized by interviews with the icon of the pornographic world John (Buttman) Stagliano, the director Tinto Brass, the artist Robert Crumb, and many still others.

The Kamasutra offers detailed instructions on how to spank it. There are those who touch it as a good luck charm before a bet. In America it is subjected to plastic surgery at a rate that almost equals breast augmentation. The female butt - let's call it derriere, butt or B-side - has always inspired wonder, fantasy and submissive devotion.
