Generalstereo Vis-ster Stereo Viewer

Italy, 1950s

This rare viewer was the only one manufactured by Generalstereo before they were acquired by I.F.A.S. The early version of the viewer actually has the company name “Generalstereo” on the viewer underneath the word “Vis-ster”. However, the later version (shown below) just has a blank space in that spot. There’s also a mottled brown version in addition to the black one shown here. Generalstereo also produced reels in the early 1950s.
