VR as an Educator

Came across an old sterograph captioned: “The stereograph as an educator ":

"Underwood patent extension cabinet in a home library … Photograph shows a woman viewing stereographs in her home; she is sitting in front of a fireplace with a cabinet for stereographs on her right.”

So I printed a copy of this sterograph and taped it over a hold cut in my Google Cardboard. This turns the virtual reality device into an old fashioned stereograph, showing VR from the Victorian era. ;-)
