Small Oil Painting, Signed "Van Holt

This is a small oil painting, measuring 5" x 3 1/2", it has been framed in a green velvet frame with a light faded green cloth, which is mounted on card. I have removed the back, and it looks like card, I have been told that it could be on a copper plate, but unless I take the fixture clips off at the back, I can not say for sure what it has been painted on, I do not want to damage the actual painting so have left it in place. It is painted in oils, and the style is of the "old school", and depicts a female figure in the foreground, a large old tree and a European looking castle in the background.There is a signature which reads "Van Holt" This painting is behind glass and the colours are very good and the artist has created a very attractive image.
