Vintage Key Stereoscope For Optician/Ophthalmologist For Sale

This is an awesome stereoscopic viewer with optician cards. It has a slider that\'s meant to hold and adjust the images from the included optician cards. It\'s meant to help correct problems with vision. It also has small slide holders for the half-images that come with it. I don\'t know if the cards are a complete set - I can\'t find information on it. But they are both color and black and white and truly awesome.
For more info, please see photos.
