In talking with my daughter after a recent trip to London, she asked the question about where the 'Keep Calm & Carry On' poster came from. My first response, "The Internet", did not seem to satisfy her, so I then told her I did not know, but would look into it.
After a few searches here and there I came across this video describing the secret journey from war propaganda to meme. It is a lovely story in how a message travels across the globe, some a simple, humble beginning. Figuring that many of you may not know the history of this passed along phrase, I have posted the video below. Enjoy.
