This is a small painting in a wood frame. It is signed "Wilkie" It is of 2 nuns at an art gallery. One nun is looking up the other's robe. The painting is aprox 4" x 5". The frame is about 9" x 10". The painting appears to be in pretty good shape, but I do not know what to look for. It is dusty and could use a good cleaning. The wood frame is in good condition but has some typical dings, dents. I have shows a picture of the frame with a few chunks out of it. I have not tried cleaning it at all.
