Photography auction estimates are always a bit confounding, aren’t they? Some spectacular specimens are up for auction at Phillips de Pury on April 4th — Man Ray, Brassaï, the good stuff. Also, a nubile naked Madonna by Lee Friedlander from 1979, pubic garden full bloom and all (below, NSFW).

She’s estimated at $20,000-$30,000, exactly the same as Frederick Sommer’s shot of a bloody ripped-out chicken bit, head to gizzard. Surprisingly, Richard Avedon’s Andy Warhol with his scar-riddled torso is cheaper, estimated at $12,000-$18,000. Yet, not even famous young breasts can compete with Diane Arbus because she brings out triplets. Triplets! That’s 33% kitch-creepier than a standard Arbus!
