More than a dozen works by the elusive British graffiti artist Banksy are among a collection of street and contemporary art up for auction in Los Angeles next month.

Axar.az reports citing to Reuters Banksy's "Umbrella Rat," an original aerosol stencil of a rat holding an umbrella that was found on a metal door in Berlin, is one of the top items on offer by Julien's Auctions, estimated between $30,000 to $50,000.

Michael Doyle, an auctioneer at Julien's Auctions, said "Umbrella Rat" could fetch as much as $100,000.

"Most of the time these (works) get covered up by the city or different private building owners so it's very rare to find an existing piece of street art that is actually from the streets," said Julien's auctioneer Michael Doyle.

Other Banksy works expected to go under the hammer at the May 11 auction include "Black Bobby," a 2003 black aerosol stencil of a British policeman estimated to fetch between $20,000 and $40,000. A 2004 screenprint entitled "Bomb Love," of a girl hugging a missile, is expected to fetch upward of $5,000.

British artist Banksy - who is presumed to be a man but has kept his identity secret - rose to prominence through the Bristol street art scene in the west of England.

He is known for creating works on buildings displaying ironic and provocative social commentary, and political stunts such as his recently opened 'Walled Off Hotel' in the Palestinian city of Bethlehem.
