Banksy is an anonymous English graffiti artist, political activist and film director. Their satirical street art and subversive epigrams combine dark humour with graffiti executed in a distinctive stenciling technique. Banksy’s name and identity remain unknown – it has been stated that the reason for this secrecy is that graffiti is a crime. Banksy’s stencils feature striking and humorous images occasionally combined with slogans. The message is usually anti-war, anti-capitalist or anti-establishment. Subjects often include rats, apes, policemen, soldiers, children, and the elderly.
