1939 from may to June, under the sudden attack of the german armored forces, the British and French allied forces retreated in Dunkirk and fled back to Britain in a hurry. At that time, Britain expected that Germany would quickly organize a landing across the sea, so in order to cope with the possibility of German occupation of Britain, a set of three morale-boosting posters was printed:

British poster

Stay calm, reading Jane Austen is a tribute to the first poster "Stay calm and stick to it".

The other two are "Freedom is at stake, defend it with all your might" (* * printed 400,000 copies) and "Your courage, your cheerfulness and your determination will bring us victory" (* *).

Because Germany lost the air war against Britain, it gave up the sea lion plan to land in Britain. These posters printed in advance in Britain were useless in the end, and most of them were secretly destroyed. It was not until 2000 that the poster of "Keep Calm and Move on" was found in the bookstore again and spread quickly. In the process of circulation, Keep Calm and Keep Calm has been preserved, but the content behind it has been spoofed and changed into various kinds, and reading Jane Austen is just one of them.
