In street art it is images that dominate rather than text. Like graffiti, street art is created illegally. Unlike graffiti, however, it aims to broadcast messages. Mere names, to the fore in graffiti, do not have a role to play here. Quite deliberately, street art is to be found in places that fit in with the message or the form of presentation.

While graffiti, as a rule, is restricted to the use of markers and spray cans, street art comprises a fair number of techniques. The best known of these is based on the use of stencils – (pochoirs). Apart from that there are murals, paste-ups, fly posters and cut-outs, small-scale stickers, and mosaics and sculptural works.
