Trying To Locate A David Rosenthal Painting Of Wonder Lake, Alaska In The Fall With Mt. Mckinley In The Background

I saw this painting several years back in some of the stores in Alaska especially around Denali. I called Rosenthal and he said all the paintings were sold out, but would consider buying a copy if in fact one is still available. I have tried googling under his name along with Wonder Lake without any success. Realize that this is indeed a long shot, but still worth a try.
