Street Art is any kind of art performed in public. The term street art or the more specific post-graffiti is used to distinguish contemporary public-space artwork from territorial graffiti, vandalism, and corporate art. ‘Street’ artists do not aspire to change the definition of an artwork, but rather to question the existing environment with its own language. Some people have a saying that the street art is all art on the street that’s not graffiti. Most popular names of the street art are Edgar Mueller and Kurt Wenver.
