In 2003 in an exhibition called Turf War, held in a warehouse, Banksy painted on animals. He later moved on to producing subverted paintings; one example is Monet’s Water Lily Pond, adapted to include urban detritus such as litter and a shopping trolley floating in its reflective waters; another is Edward Hopper’s Nighthawks, redrawn to show that the characters are looking at a British football hooligan, dressed only in his Union Flag underpants, who has just thrown an object through the glass window of the cafe. These oil paintings were shown at a twelve-day exhibition in Westbourne Grove, London in 2005.

In August 2004, Banksy produced a quantity of spoof British £10 notes substituting the picture of the Queen’s head with Princess Diana’s head and changing the text “Bank of England” to “Banksy of England.” 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.

In August 2005, Banksy, on a trip to the Palestinian territories, created nine images on Israel’s highly controversial West Bank barrier. Banksy held an exhibition called Barely Legal, billed as a “three day vandalised warehouse extravaganza” in Los Angeles, on the weekend of September 16. The exhibition featured a live “elephant in a room”, painted in a pink and gold floral wallpaper pattern.

In April 2007, Transport for London painted over Banksy’s iconic image of a scene from Quentin Tarantino’s Pulp Fiction, with Samuel L. Jackson and John Travolta clutching bananas instead of guns.

In late August 2008, marking the third anniversary of Hurricane Katrina and the associated levee failure, Banksy produced a series of works in New Orleans, Louisiana, mostly on buildings derelict since the disaster. His first official exhibition in New York, the Village Pet Store And Charcoal Grill, opened October 5, 2008. The animatronic pets in the store window include a mother hen watching over her baby Chicken McNuggets as they peck at a barbecue sauce packet, and a rabbit putting makeup on in a mirror.
