I do not know what you have but, I picked a beautiful picture of a horse and farrier in front of a big red barn, I knew it was old, but did not know what I had, I went on EBAY and started looking turned out it was a P. Detlefsen painting called horse and buggy day. It is not worth much to anyone else, but I would not sell it for the world. So I can tell you try
EBAY it might be helpful in finding what you have. Best of luck to you in your search.
