One of my favorite places in the national open air museum Arnhem is Dingenliefde. In this exhibition room, you can find collections of people like me and you. This time there was a collection of piggybanks. When I looked at them, I found a couple of piggybanks that are shaped like a mailbox! How nice is that. I would love to have a piggybank like that, so that I can safe some money to buy stamps and other things for letter writing!
