Something unusual.
Vintage eye testing stereo Realist slide by the Stereo Optical Company (Chicago IL).
I have a few of these for sale. Please look at the pictures. Some of them are strange. They test for a number of things like stereopsis, convergence, etc.
The slide is mounted in glass and a EMDE aluminum mount with aluminum frame.
The glass might be cracked, so look at the pictures. And make sure that you check my other listings for similar or unusual stereo slides.
See my other auctions for more interesting slides!
If you need a stereo Realist viewer, you can buy an inexpensive one from my ebay store.

If you want me to combine shipments, wait until all the auctions close and then request an invoice. I do not require immediate payment for fixed price items, so if you want to buy fixed price items, add them to your shopping cart and then request an invoice (it is a button hiding somewhere at the top right of the page). If you pay for something, I have to ship within 24 hours.
My only "fine print": If you have a problem with your purchase, please let me know as soon as possible and I will try to make it right. Please do not leave non-positive feedback (including neutral) or anything less than 5 star rating without contacting me first. I will do my best to resolve any problems. I accept returns for most of the items that I sell. I always leave positive feedback. I appreciate your business and I hope to see you back!
