You see these "keep calm" posters everywhere... i was interested in the origin. "Keep Calm and Carry On was a propaganda poster produced by the British government in 1939 during the beginning of the Second World War, intended to raise the morale of the British public in the event of invasion."
This poster was initially produced by the British Ministry of Information in 1939, at the beginning of the Second World War. The poster was third in a series of three; designed to raise the morale of the British public in the event of an invasion, it saw little distribution as very few were printed. In 2000, an original copy of the "Keep Calm and Carry On" poster was rediscovered in Barter Books. At the time, this was one of the only two known surviving posters outside government archives.
