I received this original postcard in four parts (a, b, c and d).
Phillip (the USA) posted one piece of this jigsaw every day, at the end of 2015. Of course, they did not arrived in the right order. The second part arrived on 13 January. The rest of the postcards arrive together two days later. In the links above you can see every part and the postmarks.
I love this kind of jigsaw experiments!
