An amusement for all
Stereographs, a pair of nearly identical images positioned side by side on a card, were popular from the 1850’s well into the 20th century. When looking at a stereograph through a stereoscope, the viewer sees a single image that appears three-dimensional. This stereograph is of a bank located near Portland’s Casco Harbor. This image was likely taken after Portland’s devastating 1866 fire.
