Peter Blake illustrates Dylan Thomas's Under Milk Wood

A year-long festival of events to mark the centenary of the birth of poet Dylan Thomas starts with an exhibition of illustrations by artist Sir Peter Blake from his study of the play Under Milk Wood.

A special programme, Under Milk Wood in Pictures, is being broadcast by BBC Wales on Monday which charts Blake's 28-year project and includes contributions from Cerys Matthews, Damien Hirst, Ronnie Wood and Pete Townshend.
