This poster meme hails from a poster designed by the British, but never actually published, during World War II. Keep Calm and Carry On was supposed to boost morale and clearly did a very good job at tapping into the national psyche.

Perhaps that’s what deviant artist smmorela had in mind when they designed this alternative.
Mind you; what about the other three!
