Early 20th century Large Bevelled Reverse Etched Mirror 60"x42". Very Few, Very Small Defects, this item is in excellent condition for its age. Markings on back show that this item has been stored for safe keeping on different occasions (one has a storage date of 10/29/52). In attemps to determine the age of this piece, i came across a Patent Pending for AdjustRite Hanger. This patent was pending Between years or 1916-1918. These Mirrors were not being made until the 1930's and mass produced in the 1940's. So i think the back frame is years older than mirror
