That's a great piece. As far as value it's hard to tell. So much makes a difference with wall hangings. If there's any kind of water mark on it you won't get anything at all for it. That goes for the Frame also. Heck I'd just hang it up and be happy you found it. Have a great day.
marble collectors love that picture...5 or 6 years ago the little girl was at a midwest marble show...her name was ruth (i cant remember her last name) i think locke...she was in her 80s and signed a picture for me...ive since sold it to another collector....the boys were all gone at that time and i believe ruth has passed away ,too....
