Hey guys, so I just came across a pretty unique piece of history. This is a monacle that was used by the late Salvatore Dali. From what I know it was crafted in the late 1950's. The person whom owns it says it is worth big bucks. Has anyone seen a monacle like this? I threw it in the lensometer and I cant get a good reading, anywhere from -12.00 to -15.00 with some centrifugal rings on the lens that are distoring the diopters, it in a way, it looks like a fresnel press on. Anyway here are some pics, if anyone is familiar with anything like this please message me. I want to know if it is a one-of-a-kind item and really worth any real money. Also if any collectors out there are interested shoot me a message. Thanks in advance for any info!
