If you go into your old antique guides you will see that icons were obtainable in this country and most of them came from the Orthodox Russian and Greek people of faith and were, and still, are highly treasured as works of art. The fact that there are so many tourist versions does not eliminate the absolute possibility that this could be an authentic icon. It may well be, but I do not see any authority here that can, beyond doubt, disprove it. If I have offended someone I apologize, but, I have seen Russian icons, as rare as they are, turn up at auctions and other markets with absolute authenticity.
