Recently, I posted two views of the old Annisquam Cotton Mill, showing it before and after the 1882 fire that destroyed it. This real-photo postcard is another view of the mill’s ruins.
The perspective appears to be looking west from the corner of Broadway and Mt. Pleasant Street, with Broadway to the left in the photo and the photographer situated on Mt. Pleasant near T-Wharf.
The ruins were removed in 1904 — 22 years after the fire. That is only a year or two after real photo postcards were introduced. Thus, the photo must be from 1903 or 1904.
