All about Keep Calm

Keep Calm and Carry On was a motivational poster produced by the British government in 1939, beginning World War II, to be used only if the Nazis could invade Britain. The poster was distributed only in limited numbers. In 2000, a copy of this poster was rediscovered in Barter Books, a used bookstore in the town of Alnwick, England. The building is now in the public domain and can be seen in interior design. The creator of the poster is not known.
