A photo of Keith Richards from this series shot in 1999 by fashion photographer Peter Lindbergh and up for auction at Christie’s in London is expected to go for at least $66,000. A David Bailey shot from 1969 of a nude Roman Polanski with pregnant wife Sharon Tate, on the other hand, is estimated to fetch only $11,000, and a calla lily shot by Robert Mapplethorpe could sell for as much as $152,000. Go figure.
