I'm trying to find out any information about a painting my parents have. It's been in the house since being passed down from my great aunt (born late 1800s). This is one of two paintings we have that are framed the same way. The frame is 19.5 wide and 16.5 tall. I've attached pictures below showing the front and back. The plaster of Paris frame extends into a black wooden box frame with a protective glass piece.
