The British Library is not alone in devoting space to the dark arts of propaganda this summer, as the British Museum also has a display — based on the same concept, but the two displays compliment rather than overlap.
A period that was marked by invasions, occupations, former colonial powers and revolutions — each calling for messages to rally the troops.
There is something strangely alien about the art work though, as while you can look at some of it and nod in familiarity about the underlying concepts, much of the design and structure of the posters are totally different to anything we are used to.
In a way, being often militaristic propaganda presented in what seems a strange art form is therefore more profound and uncomfortable.
Of course some of it looks familiar to our eyes, until you notice that Mao is also in the picture.
The exhibition is in Room 91 at the rear of the museum, is open until the 1st September and is free.
