Often associated with street art, graffiti painting takes its inspiration from urban culture. Although graffiti has been slow to make its way into the mainstream art world, it is now considered a genre in its own right. Banksy and Shepard Fairey, amongst other famous artists, have specialised in this genre of art. Initially with paintbrushes and later with aerosol cans, these artists cover the streets, and their artworks, with graffiti. Whether artists have a political agenda or just an artistic one, graffiti is a huge movement in modern and urban art.
