Yahoo.com: A full-frontal, nude photo of a 20-year-old Madonna fetched $37,500 at auction Thursday, an apparent record auction price for a photograph of the superstar singer. An unnamed European buyer bought the picture, which had been expected to sell for up to $15,000, according to Christie's auction house. Madonna, then known as Madonna Louise Ciccone, was a dancer trying to make ends meet when she answered a newspaper ad seeking a nude model.
