A man, woman, and child play on the beach in 1889.
This photo was printed on a stereographic card – basically two copies of the photo side-by-side – and was meant for use in a stereoscopic viewer. Popular in the 19th century, the viewer created the illusion of a 3D image and worked exactly like a Viewmaster toy does today.
It’s neat to think what this image would look like when viewed the way it was meant to be, in 3D!
