Ornate Round Bronze Metal Mini Picture Frame, hand painted portrait For Sale

Round bronze picture frame, late 19th early 20th Century Vintage, glass front and Portrait of an 18th century lady, probably watercolor.
This looks very French, though there is not any marking that I can find. This is how I found it, and I am hesitant to try to clean it, I prefer to leave it be. It is about 2.25 inches Round, the trim on the top gives it a little more height and makes it about 2.75 inches tall. Please see the photos and ask any questions that you may have, I will try to answer as soon as I can. Thank you for visiting my listing!
