Yeah - I was working in the Caucasus and had a set of FAA 1:1million charts of the area - the Russians had never seen anything like it - but I was warned that if "the Authorities" saw it I'd have a chance to explain at great length & personally why I had them. They really couldn't believe I'd bought them in a shop.............. I did tell them the Russians had similar maps of the West - that they were pleased to hear...... tho ' it didn't stop a few "heart-to hearts" with various Organs of the State elsewhere...
here's another (non Russian) Autonomous "Republic" - don't expect it to last long
