I call this one "Young man with a hat." Possibly this is a young man graduating..maybe from the 8th grade? He looks a little young to be graduating from High School. The Moilan Photography Studio in Duluth was only in business from 1910 to 1911. The Minnesota Historical Society has a great page that lists photographers and their locations and the dates they were in business in Minnesota. Not all photographers are listed..but most are. I have found their site very helpful.
