The design for the Omnium was Lucien Bize’s first patent and dates from 1904[1]. It’s a simple folding stereoscope for paper card stereoviews. There were also models with a frosted glass to view glass stereoviews. The viewer comes with its original burgundy coloured box. The viewer is collapsible and the handgrip can be unscrewed from the viewer part. Focusing is done by a knob on the bottom that slides the card holder forwards or backwards.
