Perfect Duluth Day

Duke of Duluth?

Superior isn’t the only city that enjoys its suds. This photo was bought at an auction several years ago. On the frame, it is titled “Duke of Duluth.” I know it is not the Duke of Duluth I am thinking of. Notice the great detail of flies on the beer mug. Does anyone one have a clue as to who this guy was? The framed photo served as a traveling photo for a long list of jolly fellows. The name written on the cardboard backing is Gust. Munding, Rush City Minnesota. Was this part of a beer campaign?
