This antique Mirrorscope was made by the Buckeye Stereopicon Co, Cleveland ohio circa 1912. This is one of the improved models with the addition of 2 heat stacks directly above the bulbs. it was designed to let the let escape while preventing light from entering. the items to be projected, postcards or photos, are illuminated by 2 bulbs. While this true antique lights up, I haven't been able to get it to project an image. It might need a mirror, it appears to be missing a part. It could be an easy fix, if you know what you're doing, i don't. it's still a wonderful conversation or decorator piece. It's 13'' tall x 17'' wide x 16'' deep.
