Cool posts people! Bahnposts are fun to find. The old postcards are very cool as well. There is a postcard show coming to town on the 8th, and I plan on going to see what treasures may lurk there. As I understand it, BAHNPOST may mean depot as well as railroad. It has a few other variations of meaning depending on country of use.
