After so many bridges sent, Heleen (the Netherlands) was flabbergasted to discover that she had never sent her favourite bridge to me: the Waalbrug, an arch bridge over the river Waal, in Nijmegen.
It was worth waiting, because I received not only one postcard, but two, and added perfectly matched stamps:
On the left, an illustration by Sieb Posthuma. The night picture (also on the postcard) is by Quinta Buma.
The third stamp, received on another postcard, keeps me intrigued: is there a stamp inside a stamp?
