Banksy

British graffiti artist, Banksy known for his antiauthoritarian art, often done in public places.
his work involved with political issue and social issue, such as anti-war, anti-capitalist or anti-establishment. Subjects include rats, monkeys, policemen, soldiers, children, and the elderly.
what is so great about him is he thinks about the message that puts on the public, after people see it, they understand the meaning immediately.
He works have been gone mainstream in modern art world, the reason is it speak the truth about the world. persuading people to accept our ideas and do what we want them to do is a basic universal human activity, but as people we have ability to change that by becoming knowledgeable, so no one can fool as.
