Antique black Lamier Paris opera glasses. I could only assume that these once belonged in a large haunted mansion in Paris. :) Missing the rim of one eye piece and lots of wear, these would be a spectacular display piece! At the large end, there's even a compass between the two glass pieces. :) These are so beautiful to keep on a book shelf, as a store display, etc. I would not use them for the opera as I'm not sure how much you'll be able to see. :) They measure approx 4 by 5 inches.
