An unusual painting is expected to fetch more than $2.3 million when it goes up for auction this month.
"The Holy Virgin Mary" was painted in 1996 with lacquered elephant dung. It was first displayed in 1999 at a museum in Brooklyn.
The artist, Chris Ofili, says he takes pride that the materials he used, came "from the earth."
It goes up for sale June 30th at Christie's.
