British propaganda from World War 2. Britain recreated the Ministry of Information (MOl) which was initially created during World War 1 to distribute propaganda in order to help the war effort. One of their most famous posters to boost British morale was "Keep Calm and Carry On" which was first printed in 1939. Although 2.45 million copies were printed, the posters were rarely seen in public and nearly disappeared into obscurity until it was rediscovered in 2000 at a second-hand bookshop in North England called Barter Books. Since then, the slogan has entered pop culture and has been slapped on numerous merchandise. It was believed that only 2 original copies survived the war, however, in 2012, the daughter of a Royal Observer Corps member brought in 15 posters to the Antiques Roadshow. The posters were appraised at £1,000 each.
