Zeta Eye-Comfort Unit No. 50 Complete In the Original Box with Instructions And 12 stereograph Cards
This is an unusual item. My dad tried to go into the Coast Guard but they wouldn’t let him, on account of his poor vision. I’m guessing he may have used this to try and help correct it. It’s actually kind of neat. I put it all together and tried it out and it looks real! The cards are curled a bit but they still work. The unit will be shipped to you unassembled. There are no missing parts. The copyright inside the instruction manual is dated 1943. So I may not be listing this item in the correct category.
