This card arrived in an envelope with a bunch of "stuff" that I don't know why the sender sent them to me! There was no reason given and when I asked for an explanation of what they are I didn't get one. So, it's a mystery.
Tini wrote in all caps;
Greetings from the beautiful old hanseatic town of Stralsund. In our city about 57000 people live. My home town is a UNESCO World Heritage Site. All the best

The "stuff" that Tini sent. I'll pass the stamps on to a friend but the sports cards? No idea what they are for.
