Well, here are some examples of stamps issued by the Polish Information Center in New York.
There are also some postwar stamps encouraging people to help relocate Polish Displaced Polish Persons ( DP's)
I will post other philatelic items ( no pun intended) here in the future.
Exile postcards, POW postcards, concentration camp mail, etc.
Please contribute what you have in your collection.
I do hope this is in keeping with the Forums mission.
