Banksy has been given a taste of his own spray paint after one of his pieces was vandalised by fellow graffiti artists.
Just days after he daubed his work on a wall in Hendon, someone spray-painted over the word PRICE-LESS.
They intended to remind Banksy of what urban art was all about, something he may have forgotten through his successful career.
Banksy's picture appeared about a month ago on the side of a power station at the junction with the A1 and the A406 North Circular Road. It depicts a boy seemingly marking the wall of a power station with the words 'Last Graffiti Before Motorway'. Before it was vandalised, the 15ft painting could have been worth thousands of pounds.
The price of the The Whitehouse pub in Liverpool doubled to £1million after Banksy adorned it with a rat holding a machine gun. However, it's not the first time a Banksy piece has been spray-painted. One of his works on a building in Gillett Square, Dalston, shows a young boy wearing a chain with a pendant of a gun and carrying a teddy bear in his right hand and a ghetto-blaster. Days later it was sprayed in blue, and the words 'love not money'.
There still remains public uncertainty about the identity of Banksy, who was reportedly born and raised in Bristol. He became involved in graffiti during the great Bristol aerosol boom of the late 1980s. Banksy's famous art now appears in cities across the world.
