A STEREOGRAPHIC TREASURE 
Invented by Sir Charles Wheatstone in 1838.

A stereoscope is a 3D viewer.
Photographers captured two almost identical images.
Then printed them side by side on a card.
The special lenses of the stereoscope created the dimension.

A magical source of entertainment in the early 1900”s.
Imagine the thrill of viewing grand landscapes in 3D
Taking virtual trips around the world,
Without having to leave the parlor.

Queen Victoria and Prince Albert received one as a gift in 1851.
Which certainly increased its popularity.
