A mural by the elusive street artist known as Banksy disappeared from the exterior of a London store last week and has emerged at a Miami auction.

Removed from the side of a Poundland store (similar to a Dollar Store franchise in the U.S.) was a mural now listed in the upcoming Feb. 23 sale at Fine Art Auctions.

"Slave Labor (Bunting Boy)" depicts a boy sewing a Union Jack bunting and is estimated to sell for between $500,000 and $700,000. It is described as "stencil and spray paint on render with additional jubilee bunting."

The auction house says the work comes from a "well-known collector," but has not named the consignor. London locals are demanding to know more details about the extraction of the mural that once brought visitors to their neighborhood.
