The top postcard is at the corner of Fifth Street and Pine, looking east. The Bosch Brewery building on the RH side burned completely the summer of 1990 and is still an empty lot.
The second is on the Houghton side of the old bridge. The car on the right is number 22, the same car in the previous snow photograph!
The third card shows Sheldon Street in Houghton, about 1925. The bottom photo is an original that was use for later images on postcards.
