Nothing new under the sun as they say, these are 3D images of yesteryear. They were chanced upon on a vanilla blog Pocketful of Ginch. The first two was how they would have been used the rest are details of the image as singles.

My grandmother had a stereoscope for viewing holiday snaps, but she never had anything like these images. The scope itself was red and resembled a pair of binoculars. When one is small it was like magic.

The modern versions of the scope usually have a reel of companion images which turn when one hits the lever. The model used for the images above were viewed one at a time.
