Antique Convex retailer Bubble Glass Picture Frame

Product Name: Antique Convex retailer Bubble Glass Picture Frame
This came from a 113 y/o house we purchased to renovate for my daughter. Someone painted a castle, etc on the glass but it wasn't sealed or covered & the paint is coming off. Could use acetone to remove the rest or possibly just some soap and a soft brush. There is no backing present. The wood and glass are both in good sturdy shape. It measures 22 1/2” long x 16 1/2” wide & weighs over 3 retailer pounds w/o packaging. Please look closely at all the photos for most accurate description. Thee are a few chips on the frame, which can be expected for a 100y/o+ item! Thanks for looking!.
