Book-shaped contraption resembles a mono version of a stereoviewer. It has a green leather cover with the word "MICROPHORE" in gold letterpress on the spine. A two-part metal clasp releases a lid. When opened, a spring-loaded lens is aimed at an assembly of cotton loops that could attach to small photographs.
