I have an oil painting of this that is very old; it came to me through generations ago from a catholic priest in the family. There are sketchmarks of another painting on the back of the canvas and the original frame which is wedged wood corners. There''s no visible signature but some scribblles on the back of the canvas. It is an early copy certainly if the original is confirmed elsewhere. Wondering what the market is. The colors look much darker and more brooding than the photos I''ve seen. It has been in my family more than 70 years. I''ve been inttrigued by the painting since I was a child and wonder if it''s worth anything.
