London's Ours: Radical 1980s campaigns by Greater London Council

Hazel Atashroo's new book collects the Greater London Council's poster campaigns from 1981 to 1986, the years the GLC fought racism, nuclear war and its own abolition through cheap print runs when the council itself was nearly skint. She talks it through with curator Rosamund Lily West, unpicking a visual culture built to provoke.
