This man has a fairly active auction history. However my Art price subscription has expired and can't get a figure. you may be able to get it in print at a Public Library try the reference librarian for art auction prices realized book suggestions. Go to a gallery or antique shop and inquire if they might have any reference you could use. If your selling-pay the money and have it valued properly. If you need to ask what are really visual questions include a picture and measurements.
