Street Graffiti

Radical and political
Graffiti often has a reputation as part of a subculture that rebels against authority, although the considerations of the practitioners often diverge and can relate to a wide range of attitudes. It can express a political practice and can form just one tool in an array of resistance techniques. One early example includes the anarcho-punk band Crass, who conducted a campaign of stenciling anti-war, anarchist, feminist and anti-consumerist messages around the London Underground system during the late 1970s and early 1980s.
In Amsterdam graffiti was a major part of the punk scene. The city was covered with names as 'De Zoot', 'Vendex' and 'Dr Rat'. To document the graffiti a punk magazine was started called Gallery Anus. So when hip hop came to Europe in the early 1980s there already was a vibrant graffiti culture.
The student protests and general strike of May 1968 saw Paris bedecked in revolutionary, anarchist, and situationist slogans such as L'ennui est contre-révolutionnaire ("Boredom is counterrevolutionary") and Lisez moins, vivez plus ("Read less, live more"). While not exhaustive, the graffiti gave a sense of the millenarian and rebellious spirit, tempered with a good deal of verbal wit, of the strikers.
