This is another image of a boat featured some months back. This image is closer in and in black and white, but otherwise the images are remarkably similar in that the boat does not appear to have been replaced, and the tourist still occupy the usual locations.

The boat itself is also called the Tahquamenon, as indicated by the name sign visible in the picture.
The brown marking in the upper right is damage from a decomposed rubber band. This image is hard to date, but is likely from the 1940s.
There is no description on the back.
