The fist time I received a card with a “missent” stamp mark on it was when I got BE-653853. It was from Belgium to Brazil, missent to Belize - at first I didn’t understand the stamp mark (the back of the card is all colorful and beautifully drawn) and just thought “what’s ‘Belize’ doing here?” - but ok, at least it was missent to somewhere in America, although a little to the north.
Today I got a direct swap postcard from the UK which was missent to Thailand (!) I found it really interesting because it’s a long way from Brazil.
I kinda like to find out about those adventures cards go through when traveling to us. So I’m thinking, have you ever got a card that was missent? What was the most distant place from the actual destination?
