Graffiti (original and Italian-sounding word) represents all the inscriptions, drawings, paintings, engraved, drawn or painted by hand on public or private property, on monuments or walls not provided for this purpose. Graffiti is the purely visual discipline of Hip Hop culture. This art, long considered vandalism, finds today its letters of nobility thanks to the emergence of many artists and followers of this medium, which made it a respectable art. Today, graffiti is generally associated with street art.
