Anotations

Scope note:

Stereoscopic cameras that made exposures on glass plates, and that could be transformed into stereo viewers by removing the shutter panel. Introduced in 1904 and used until the 1930s. These were marketed as cheaper alternatives to Verascopes, a similar device made by the same manufacturer.
