"This is the first publication to explore the rich history of conceptual art in Britain during its most exciting and innovative period, from the mid 1960s to the election of Margaret Thatcher in 1979. It examines how the early works of this period took the form of a challenge to art’s traditional boundaries and how by the mid 1970s, focus had shifted away from issues of art and individual experience towards questions of politics and identity, using the languages of documentary, propaganda and advertising in the service of action."--Publisher description.
