The Origins of Keep Calm and Carry On

I think we've all seen the parody posters of Keep Calm and Carry On, but I never knew where it originated. After seeing this video, the poster and its words have new meaning. I can't imagine what it was like having to hide in bomb shelters, dealing with bombings and rubble and deaths. The parodies are still funny, but the original means more to me now.

Keep Calm and Carry On.
