I walked thru my basement this evening and looked up at a print on the shelf that came to me from my grandfather who died 25 years ago. I decided to look at it closer and upon taking it apart, discovered that behind the print was a painting signed by "van Saake". The title is Florida beach. It is priced $75.
10 minutes of research led me to this site. I believe this was painted by the George Van Saake that you are conversing about. No idea how this painting came to Michigan.
