It is greatly interesting the stamp! It reminds 20 years of the opening of the border Austria-Hungary! It happened in the summer of 1989, I remember, and the East-Germans did take advantage of this first opening of the "iron curtain" to escape to the West. This episode was the real origin of the bankrupt of East Germany and, after, of all socialist states in Europe.
I got the same stamp on my last Austrian card.Need just the German one to complete.
