I think too the lettering on the first hat's label is Russian. It's a looong time that I taught myself the cyrillic alphabet, and I always struggled with reading it as soon as they used cursive letters, or when something was handwritten... I never learned the language, but I swapped stamps with someone in Russia for a time, and wanted to read what it said on them.
The big letters on the label mean "ROT-FRONT". No idea what that means - I even threw my Russian dictionary out some time ago (gee, I should have known that it might still come in handy! :damnit: ). The first word underneath the animal, or whatever it is, says "Leningrad", I would say I'm pretty sure. I can't make out the word beneath that.
This hat reminds me too a bit of the folk styles - not just the cossacks, but hats as they are worn in central Asia and the steppes - lotsa countries there that once belonged to the Soviet Union too, and maybe this hat was inspired by those styles.
