The Dutch cartoon museum or 'Het Nederlands Stripmuseum' as it is called in Dutch (funny fact: cartoon = strip) has opened in 2004 and shows many cartoons made by Dutch cartoonists. It's also suitable to visit with children (not only because there's a world-famous fast food restaurant next-door with playing possibilities), but also because they can learn how to draw cartoons by themselves.
