Pieta model found in moldy box?

Most people would not have given a second look to the junk in a moldy box in an antique shop, certainly not a small terracotta statue covered in paint and scotch tape. But an Italian art collector did look a second time and may have discovered the model for Michelangelo's Pieta. (photos)

The 12 inch high statue has now been restored and is scheduled to return to Italy for the first time in centuries.
