Lots of things are happening on the Amsterdam canals… …again! Frans Le Roux draws an Amsterdam holiday, the games that are played, the second-hand items that are sold and of course everything is for sale on the Noordermarkt. Residents hang out of their windows and enjoy and/or photograph the cozy atmosphere. People are dancing, having fun, sailing in sloops, tour boats... be careful! A mouse flies away! Oh no, what is that submarine doing there? The Noorderkerktoren on this comical puzzle completes the picture!
