Great news: The first two postcrossing postcards arrived today, one from Germany and one from Canada.
The German card was franked with the German 2022 "Postcrossing" stamp (Michel 3722) of €0.95, a new addition to my collection.
The Canadian card was an anniversary card for World Postcard Day 2022!
In the past five weeks I sent 8 postcards, 6 have already been received by their recipients and two are still traveling.
