You can see graffiti in every country in the world. It often defaces walls, poles, trains and the fronts and sides of buildings. Graffiti is considered undesirable vandalism to its victims who spend time and money to paint over or wash it off their property. Indeed, graffiti painting is an ongoing problem in many subway stations and on public walkways, signs, cement walls, and other locations.
However, on the streets of the United Kingdom near London, an artist called Banksy continues to gain international recognition and fame for his graffiti. The fact is that Banksy's "street art" has become immensely popular with both pedestrians and private art collectors alike. In the last several years, there have been a number of exhibitions and auctions of Banksy's art work as his popularity has soared.
