Sydney Laurence watercolor on Photograph, Alaska's most famous artist,1865-1940

First artist to paint Mt. McKinley, he was artist and photographer, here he painted one of his photos, back of this is Fairbanks Alaska Photo Shop printing. I saw on Antiques Roadshow his small oil paintings go for $30,000 to $50,000. This is watercolor, on photo. He was born 1865 and died 1940.
