Poster produced for British Railways (BR), showing the Gresley A4 Class Pacific Plover locomotive crossing the Forth Bridge in Scotland. Artwork by Terence Cuneo (1907-1996). Cuneo withstood gales of over 50mph to sketch this scene from a girder high above the track. He recounted: 'Working conditions here were frankly terrifying. Although swaddled in a flying suit, duffel coat, balaclava and mittens, to say nothing of long woollen underwear - I was frozen!'.
