Since then the poster has become internationally recognised and is widely associated with a belief in British stoicism and the “stiff upper lip”. After interest from customers, a few reproductions were made and sold. Manley and his wife, Mary, framed it and hung it on the wall behind the cash register. It was discovered 16 years ago at the bottom of a box of old books by Stuart Manley, the owner of Barter Books in Alnwick, Northumberland. The surviving Keep Calm print will go on sale at the fair in Olympia with a price tag of £21,250 at the Manning Fine Art stand. A year later, once Britain had weathered the onslaught of the Blitz, all the printed posters were sent back for pulping and recycling as part of the wider paper salvage drive, due to the shortage of raw materials. The poster was designed by the Ministry of Information in the summer of 1939 to represent a message from the King to his subjects, and it was hoped it would reassure the public and prevent widespread panic.
