Coats of Arms

I was checking some facts on North Korea today on Wikipedia, when I noticed something interesting. Their coat of arms seems very familiar. It looks more or less like the one Romania had during the communist regime. See for yourselves:

Romania, 20 years ago:

But then I learned something interesting. It looks like there were some design guidelines coming all the way from Moscow:

-    “You guys can have your own coat of arms, as long as it looks like this!”
-    “But, comrade… 1000 years of history…”
-    “Eeeh eeeh! No buts!”
So I went on and made a list with current and former communist countries and looked for coats of arms resembling the two above. It looks like the design recommendations worked. They all look more or less the same (Cuba's the odd one out). But most of them share a common fate: they're abandoned and forgotten.
