Keep Calm and Do Not Disturb Door Hanger

It is so important to keep calm that it became perhaps THE enduring message carried forwards into the collective consciousness of British people since the morale-boosting propaganda posters that started it all were made to keep up people's spirits during those dark years. Today, the retro chic and strong design of the Keep Calm posters have been carried forward into a myriad of variations and styles. It says something about the simplicity of it that it looks as if it were made today.
