Underwood & Underwood Stereoscope 3D Viewfinder Stereo Card Viewer, 1901
Here is a great stereoscope used to view stereoscopic 3D cards that were popular at the turn of the century. This one was manufactured by Underwood & Underwood of New York, and the latest patent date listed is June 11, 1901. It is also marked with the Sun Sculpture Studios name, a subsidiary of Underwood & Underwood. This stereoscope is in excellent working condition and operates great. There is a small piece broken off from the end of the divider between the lenses, but it does not effect operation.
