- Keep Calm and Carry On was a poster produced by the British government in 1939 as they were preparing for WWII.
- Approximately two and one-half million posters were printed.
- The poster was designed to promote a sense of call among the British citizens as they faced the possibility of air attacks on their major cities.
- Two other posters were part of the war-time endeavor . . . .
- Apparently, the posters were never actually used and not publicly displayed. 
- The poster has been reprinted by several companies since 2001.
- The slogan has been used and altered in recent days . . . .
“Now Panic and Freak Out” (with an upside-down crown),
“Get Excited and Make Things” (with a crown incorporating spanners),
“Keep Calm and Have a Cupcake” (with a cupcake icon),
“Don’t Panic and Fake a British Accent”
“Keep Spending and Carry On Shopping”
“Keep Calm and Don’t Sneeze” during the 2009 swine flu pandemic
“Keep Calm and Call Batman” (with the Batman logo)
“Keep Calm and Switch to Linux”
“The Keep Calm and Play Louder Tour” 
“Keep Calm and Wash Your Hands.”
- There is an ongoing trademark battle on the use of the slogan.
- “Keep Calm and Carry On: The Truth Behind the Poster ” is the title of the book written on the history of this poster — “Bex Lewis, author of Keep Calm and Carry On: The Truth Behind the Poster, said ‘The design of ‘Keep Calm and Carry On’ has penetrated into our everyday lives since its rediscovery in 2001. In this new book, the life, death and resurgence of the design is placed into the context of posters in the wartime period, whilst tapping into why the poster has become such a cultural phenomenon.'”
Key Biblical Thoughts:
(You can include whatever you find useful)
You can write whatever words you want on a poster, but when the bombs begin dropping, that intended calm fades fast. It takes more than posters; it takes a resolute hope in something that is as firm as rock. . . .
