A black and white photo of Madonna is up for auction at Christie's in February and it is expected to bring in $10,000!
What makes this photo so special?

The photo is about 30 years old and is kinda' erotic!
There's also a story behind the photo; a 20-year-old Madonna poses nude for photographer Lee Friedlander, after she answered his ad searching for a nude model.
This particular photo appeared in Playboy in 1985.
(I didn't post it with the article because it's NSFW)

There are other photos similar to this one, that have already been sold to Playboy back in 2003 for $7,170.
