Bob and Roberta Smith is a pseudonym for the British artist Patrick Brill, whose politically inflected art explores language and its ability to manipulate and inspire. His paintings, executed with sign makers' paints and brushes on board, take the form of slogans, such as Make Art Not War, now in the collection of the Tate in London. A provocateur, he has run for Parliament and has said, "Make your own damn art. Do not expect me to do it for you."
