School map from the scrap heap of history

I was inspired to buy a map from one of the Fretex stores run by the Norwegian Salvation Army today.

What was I thinking? It certainly wasn't what I was looking for. But back at the office I see that this map was from before the fall of the iron curtain, and that it is printed in German Democratic Republic. Although the Nordic countries are in focus, the map also contains parts of East Germany and some SSRs that since have regained their freedom. "Freedom from what?" you may ask, and I will point you here as a start. Since I don't have wall space for it at home, I think it will stay in my office.
