One of three works by the elusive British street artist Banksy has sold at a Miami auction for $US575,000 ($A638,356).
An anonymous buyer purchased Kissing Coppers, spray-painted in 2005 on the Prince Albert Pub in Brighton, England, at the Fine Art Auctions Miami on Tuesday night. The piece was expected to sell anywhere from $US500,000 to $US700,000.
Ashley Jimenez, a spokeswoman for the auction house, said the other two pieces - done in New York last year - didn't receive their minimum bids but interested buyers can still contact the auction house within 30 days.
The two works that went unsold are Bandaged Heart and Crazy Horse Car Door.
