Mutoscopes and Cail-O-Scopes!
I have seen a few antique peepshow viewing machines on tv shows but it wasn’t until recently that I discovered the names of these vintage peepshow machines- the Mutoscope and the Cail-O-Scope (not to be confused with a stereoscope, which is a handheld viewer designed to give a 3D effect to images). Created in the late 1800’s and very early 1900’s, these were coin operated machines with images on a reel, designed to give the same motion picture effect as flip books. This was a very competitive market because, as we all know, sex sells- so the designs, mechanical operations, and names vary depending on the creators and manufacturer. Not all of these machines were used as “early porn”, but that is definitely where they made most of their money!
