Found this card in a 50 cent box at St Louis Stamp Expo...I bought it for the interesting front picture.....it shows a river junction at the geographical meeting spot of 3 separate countries, Germany, Austria, and Russia. I was pretty good with geography in school, but I couldn't remember Russia, Germany and Austria all having connecting borders!! Well, as the map shows, way back in 1898 they did!!
That was surprise number 1.
Surprise number 2 is on the reverse side.....it has 3 stamps, one from each country, as if the sender wanted to remember this geographical spot and associate it with the stamps. Maybe he knew there were 2 world wars coming that would alter this borderland drastically....



The junction of the river is just north of the mountains on the map, in the 1898 map the mountains are located on Austrian northeast border. The 3 colored borders (...red for Germany, yellow for Austria, and green for Russia) meet at this junction...but its hard to see the river path. Anyway.....obviously this is an area which is present day Poland. Just thought it was cool....
