Couple days ago I found that there is an interesting oily spots under one of his painting. In Russia we call this "Mirotochenie icon" It is very special it's like blessing.
I was making researches and I can confirm that it's not from condensation or smoking (in one of the forum I got this idea). Me and my husband are non smokers.
We got a TARO reading for this phenomena and now I need spread the word about this miracle.
