Maybe 2 years ago I started to see this poster everywhere, dating from WW2 Britain. I loved the phrase, and even made some key chain charms using it that I sell in my shop. I did well with them and only have a few left, but they hardly sell any anymore, as its moment has passed.
I was stopped in my tracks by this display last week at my local Barnes & Noble. I didn't have time to check the manufacturer, but I feel that now that it's mass marketed (the image doesn't seem to be owned by anyone), the demand will wane.
Now I enjoy the parody posters that started springing up last year....
