| | Public art - Wikipedia, the free encyclopedia |
 | | Some public art is intended to be ephemeral, going so far as to include temporary installations and performance pieces. |
 | | In some cases the line between graffiti and "guerrilla" public art is blurred, for example in the case of the early works of Keith Haring, executed without permission in advertising poster holders in the New York City Subway, and the current work of Banksy. |
 | | In many cases such public art is spontaneously created in the urban environment, often without the consent of authorities or in the case of political struggle, against the law. |
