Detroit mural by Banksy for sale

A large street mural painted on a derelict Detroit auto factory by elusive British artist Banksy is going up for auction in Beverly Hills and could fetch up to $400,000 for a local nonprofit, Julien's Auctions said on Wednesday.

The 2.1 by 2.1 meters mural called I Remember When All This Was Trees, which was painted by Banksy on the wall of the crumbling Packard factory in Detroit in 2010, will be sold along with a second large mural the graffiti artist created in Bethlehem.

The Bethlehem work, called Donkey Documents, depicts a donkey having its papers checked by an armed soldier and was one of a series of politically-aimed 2007 artworks left by Banksy along a concrete barrier dividing the West Bank from Israel.
