A piece of graffiti left on the wall of a London pub, Princess of Wales, is believed to be the latest creation by the elusive artist Banksy. Banksy is a pseudonymous British graffiti artist. He is believed to be a native of Yate, South Gloucestershire, near Bristol and to have been born in 1974, but his identity is unknown. Banksy does not sell photos of street graffiti. 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. Asked about his technique, Banksy said: “I use whatever it takes. Sometimes that just means drawing a moustache on a girl’s face on some billboard, sometimes that means sweating for days over an intricate drawing. Efficiency is the key.”
