Subjects often include rats, apes, policemen, soldiers, children, and the elderly.In July 2011 one of Banksy's early works, Gorilla in a Pink Mask, which had been a prominent landmark on the exterior wall of a former social club in Eastville for over ten years, was unwittingly painted over after the premises became a Muslim cultural centre.One of these sold in October 2007 at Bonhams auction house in London for £24,000.
His satirical street art and subversive epigrams combine dark humour with graffiti executed in a distinctive stenciling technique.His works of political and social commentary have been featured on streets, walls, and bridges of cities throughout the world.In August 2004, Banksy produced a quantity of spoof British £10 notes replacing the picture of the Queen's head with Diana, Princess of Wales's head and changing the text "Bank of England" to "Banksy of England".Someone threw a large wad of these into a crowd at Notting Hill Carnival that year, which some recipients then tried to spend in local shops.Banksy displays his art on publicly visible surfaces such as walls and self-built physical prop pieces.
Banksy does not sell photographs or reproductions of his street graffiti, but art auctioneers have been known to attempt to sell his street art on location and leave the problem of its removal in the hands of the winning bidder.
The following day's auction saw a further three Banksy works reach soaring prices: Ballerina with Action Man Parts reached £96,000; Glory sold for £72,000; Untitled (2004) sold for £33,600; all significantly above estimated values.
To coincide with the second day of auctions, Banksy updated his website with a new image of an auction house scene showing people bidding on a picture that said, "I Can't Believe You Morons Actually Buy This Shit." In February 2007, the owners of a house with a Banksy mural on the side in Bristol decided to sell the house through Red Propeller art gallery after offers fell through because the prospective buyers wanted to remove the mural.
A wad of the notes were also thrown over a fence and into the crowd near the NME signing tent at the Reading Festival.
A limited run of 50 signed posters containing ten uncut notes were also produced and sold by Pictures on Walls for £100 each to commemorate the death of Princess Diana.
The exhibition featured a live "elephant in a room", painted in a pink and gold floral wallpaper pattern, which, according to leaflets handed out at the exhibition, was intended to draw attention to the issue of world poverty.
