A rather strange "International Organisation" which I have not yet found any information on but most likely Georgian (as the text and Stalin are both Georgian). This membership card #3262 was issued to Aleksandr Artashesovich Sar'jan 19th July 1999. It's rather strange that only 8 years after the cold war the word "Organisation" is spelt "wrong".
It's not a joke - I've seen at least 2-3 other such docs and at least in Stain's birthplace (Gori), he's still considered the small-town boy who made it big.
