Duluth Boat Course
The Library of Congress has three photos on file labeled “Duluth Boat Course.” Above they are stitched together in Perfect Duluth Day’s attempt to see if they were intended to be used as a panorama. It almost kind of works.
Below are the three separate images, which show much better detail on their own. The photos are attributed to Bain News Service and dated “between ca. 1915 and ca. 1920.”
