There is a particularly interesting moment from 1940 when Superman, taking Adolf Hitler captive, threatens him with "a strictly non-Aryan sock on your jaw".
It was also a bit chilling to see America's knowledge of Belgium in the first world war reflected in a comic of 1914.
There is lots of lovely art.
Also, Batman and Robin now have competition.
You have plenty of time to catch it - it's on until 26 April (my birthday). It's at Rue des Minimes 21, just off the Grand Sablon.
