Antique stereoscope from the American Stereocopic Company circa 1905 with a lot of 60 stereoscope cards. The stereoscope is in very nice shape for its age, with a less common black metal eye piece that has light colored ornamentation and the original felt on the rims which is worn off some but mostly intact. A few small dings and scrapes to the metal but quite nice and original. The wood is also in looking good with a few short "worm trails" and scant traces of past water/humidity damage but no cracks or structural damage. The movable crossbar and central keystone piece are newer replacement parts, everything else appears to be original. Some of the stereoscope cards are old, most are a later series showing travel architecture. The stereoscope is marked with a few patents in 1902, 1903, and 1904.
