During World War II, the British Government temporarily commissioned a group from the government to generate propaganda to boost the morale of British citizens. The first two posts said, ‘Your Courage, Your Cheerfulness, Your Resolution will Bring Us Victory’ and ‘Freedom is in Peril’. After that they made a third poster which was never released. It said, ‘Keep Calm and Carry On’. The purpose of this poster was to calm the citizens if Germany invaded Britain. Nearly 60 years after the war, a poster was found by a bookseller.
This poster is part of an ecology because its audience has shifted from time periods, and it holds thousands of meanings in our modern times. I personally know many people who think this poster is just about finding zen. There are also plenty of people who know this poster from memes. If you simply search google everything from “Stay Alive and Avoid Zombies” to “Now Panic and Freak Out” have replaced the original saying. Depending on one’s perspective, they can look at this poster and see something unique. Thereby, affirming that this poster is part of an ecology.
