Original political poster, The Firth of Clyde, by Peter Kennard, 1983. Hand singed by the artist. The design features a black and white photomontage based on an historic postcard of the Firth of Clyde with a Trident nuclear submarine inserted to occupy the central pane. (His Majesty's Naval Base, Clyde, is the Royal Navy's headquarters in Scotland and is best known as the home of Britain's nuclear submarine fleet).

This poster was one of eleven small format posters issued by the Greater London Council with the series title 'GLC Peace Posters Pack’, designed by Kennard with a foreword by E.P. Thompson. The first print run of 800 packs were sent out free of charge to various anti-war and anti-nuclear groups, community groups, schools and local authorities around the UK. A second print run of 2000 were later produced to meet popular demand.
