Working Kodak Stereo Camera with original leather case.
I purchased online about three years ago, and I shot a roll of film before deciding it wasn't for me. The photos are "meant" to be viewed through a stereo viewer, which can still be found online or maybe in your parents' attic.
Examples photos (one through each lens) are included. The aspect ratio of the photos is roughly square, but I scanned them at a regular size which is why you can see the edges of two other photos in each example photo.
