Rare antique stereoscope card by master pioneer photographer Charles Emery. This 3d photo is a cityscape image in a series he produced called "Views of Rocky Mountain Scenery, Scenes along the line of Denver & Rio Grande Railroad", I have several others rare Charles E Emery stereoviews listed too. The title of the photograph is handwritten on the back which intimates that these may be his first originals. This particular one is of the Public School in Silver Cliff Colorado. The scene shows all the kids and teachers lined up outside the L shaped school for the first class photograph of its kind. Some of Charles E Emerys works are currently on exhibition at The Annapolis Collection Gallery, Annapolis, MD.
