For your consideration I have an ultra- rare mechanical advertising mirror identified as the C.D.Kenny Company that dates from 1895. This 2 ¼ inch diameter mirror was an advertisement for C. D. Kenny coffee. A photographer stands beside a view camera. His arm is on a pivot and when the mirror is tilted he removes and replaces the lens cap from the camera. It is marked D.R.G.M. that indicates the design was registered in Germany. The year 1895 is accurate given period catalog advertising through this company that highlights this unique design. There are only a handful of these mirrors that have survived.
(very good condition)
