Train Graffiti

"I think graffiti writing is a way of defining what our generation is like. Excuse the French, we're not a bunch of p---- artists. Traditionally artists have been considered soft and mellow people, a little bit kooky. Maybe we're a little bit more like pirates that way. We defend our territory, whatever space we steal to paint on, we defend it fiercely."
Sandra "Lady Pink" Fabara
The developments of graffiti art which took place in art galleries and colleges as well as "on the street" or "underground", contributed to the resurfacing in the 1990s of a far more overtly politicized art form in the subvertising, culture jamming or tactical media movements. These movements or styles tend to classify the artists by their relationship to their social and economic contexts, since, in most countries, graffiti art remains illegal in many forms except when using non-permanent paint. Since the 1990s a growing number of artists are switching to non-permanent paints for a variety of reasons—but primarily because is it difficult for the police to apprehend and for the courts to sentence or even convict a person for a protest that is as fleeting and less intrusive than marching in the streets. In some communities, such impermanent works survive longer than works created with permanent paints because the community views the work in the same vein as that of the civil protester who marches in the street—such protest are impermanent but effective nevertheless.
In some areas where a number of artist share the impermanence ideal, there grows an informal competition. That is, the length of time that a work escapes destruction is related to the amount of respect the work garners in the community. A crude work that deserves little respect would invariably be removed immediately. The most talented artist might have works last for days.
