Словения 2016 (Joint issue with Russia):

One of better design in Slovenia postage stamps!
It is Joint issue with Russia, from 2016 year.
Michel catalog have it under number 1212, and in, I can say, low catalog value of 10.00 euro for small sheet, in mnh condition.
If we know, that total quantity printed is 60 000 of stamps, mean, it is some 10 000 small sheets, and very popular topic (Churches), so, we can say, that it is affordable price, even if You pay full catalog value for small sheet!
