Father, Bless!
You have a copy of the icon shown on Our Lady of Fatima Russian Catholic Church webpage or you have a copy of the icon Dr. Roman mentions in his article. OR are they the same?
Do you have a scanner or picture of the icon you have? Or might you have any way of pointing me to a picture of it online?
The Fatima icon is actually a variant of the "Joy Of All Who Sorrow" icon, which appeared in Russia before the revolution. The iconographer who wrote the Fatima icon used the "Joy Of All Who Sorrow" icon as his model and simply added the figures of Lucia, Jacinta, and Francisco.
I have the Fatima icon as a jpeg.
Just PM me with an e-mail address and I will send it you.
