The Canal—Portage Lake. The scene shows the northern canal leading under the bridge from the Huron River into Portage Lake.
Both postcards are of the same scene of the canal connecting the Huron to Portage Lake. The top one is a real photo postcard, the bottom one an Albertype, probably using the same original image for printing. On an Albertype card, details could be added or taken out, blended or enhanced. The cloud formations were probably added to the original image.
