@bgoods55,
Huh - I wish I knew something about this, and I'm sorry I don't. The age of the seller (from the estate) might or might not support the idea of it being a relatively older piece, but who knows? Is there an antique shop in your area? Maybe bring it over and ask. They'd do better if you brought in the picture, rather than photographs of it, as they could take a look at the frame as that can sometimes provide clues.
