Mystery of the Cold War Map

So today I was in science class and I pause to look at a map. It isn't too interesting. I look at how much the 3D alps stick up towards me I remember something from a few hours ago. ...puppet state...soft underbelly of the...Winston Churchill...axis troops...excellent defensive positions. I decide to look at the Balkans since I'm bored and looking over maps amuses me. Then I saw it.

Yugoslavia

Unless you know a lot about Eastern European history you wouldn't know why this is so odd. Yugoslavia was made after World War I it pushed a lot of ethnicity's into one country and was a terrible idea. This is why the country no longer existed, it was now lots of smaller nations such as Macedonia, Croatia, etc. What puzzled me was that Yugoslavia had been gone for a long time the nation only lasted between WWI and the Cold War Era. So I turn my attention to Russia and see in bold letters:

Union of Soviet Socialist Republics

AKA the USSR AKA Soviet Union AKA Soviet Russia. So I realized standing there in science class that this map must be really old. Maybe from the 60s. But oddly enough Germany appeared to be one whole country. Very curious indeed.

Well that's your interesting tidbit of my life today. Hope this didn't bore you too much.
