A. Steve,
This is not something that we would purchase, as we phased out most wildlife art and stamp prints several recessions ago.
Sadly much of the wildlife "limited Edition" scene is loaded with hype and questionable printing. Although there are exceptions, the demand currently is fairly low.
Your image by William Koelpin, although not known outside of Wisconsin, is a very nice print, Monitor Ebay for some time to determine what this might realize in a sale.
Sincerely,
