Turner Prize winner and official war artist Steve McQueen, in collaboration with 137 families whose loved ones have lost their lives in Iraq, has created a cabinet containing a series of facsimile postage sheets, each dedicated to a deceased soldier.
Visitors are invited to take part in Steve McQueen's vision and sign The Art Fund's online petition asking the Royal Mail to issue the stamps.
Previously exhibited at the Imperial War Museum.
