I was doing a little research today and I ran across an image that caught my eye. Digging a bit further, I discovered the image source was from Keep Calm-o-matic.
The Keep Calm-o-Matic is the place to express your creativity, dreams and imagination. You can create, discover and shop.
They make a variety of customizable products based on the WWII poster used throughout England to encourage their citizens to carry on in spite of the rocket attacks and bombings from the Nazis. (The website is so easy and engaging I bought a customized poster and a coffee mug and I do not even drink coffee.) See for yourself at http://www.keepcalm-o-matic.co.uk
