I love almost all kind of nuts! It was a nice surprise to receive this "nut" card from some nuts from Netherlands! :D Too bad the stamps were not cancelled, they are so beautiful they deserved more!
Another good example from the country of tulips and windmills. The 2 donkeys are french but the lovely stamps are definitely Dutch! Another amazing official card from Postcrossing.
Another official card, now from China. The Aurora Borealis stamps are amazing!
Last but not least, an official from Belarus. Amazing stamps!
