Leningrad Stereoscope
Russia, 1950s/1960s
Both Leningrad stereo viewers used multi-pair stereoview cards that are inserted in the top of the viewer and advanced through the bottom. They both also resemble French-made stereo viewers. The early version, made in 1950s, was very similar to the Colorelief viewer and the later version, made in the 1960s, is almost exactly the same as the Bruguiere Stereoclic.
