RaroEste is a very good example of the folding pocket stereoscope IMPERIAL No.157580 by D.R.G.M. in or around 1905. This rare viewer is in its original case and has the original IMPERIAL twenty-five (25) piece set of real photos stereoviews. The stereoscope is made of tiny tin with a lithographic exceptional graphics. Measures only 4 1/4 inches by just over 3 inches at the base when set for display and has a height of 1 ½ inches you. The stereoviews measure only a 2 3/4 inch by 1/4 inch. The graphics of this rare tin toy are exceptional for his age. Original box measures 6 x 3 3/8 x 1/2 inches and has a slight wear. The details of lithography inside the box are nice and it is rare to find this toy in its original box. The twenty-five (25) stereoview photos are titled in German, so I can not describe the scenes shown. I was told that these sets were used by IMPERIAL advertising promotions CHOCOLATES.
