Tray-Stereoscope ‘Planox Apéscope sur socle’ with Storage Cabinet

The Apés­cope is one of the few hand-held mul­ti-view stere­o­scopes and a late devel­op­ment, pro­duced at a time when stere­oscopy was in decline. A mag­a­zine con­tain­ing 12 glass stere­oviews can be insert­ed into the view­er from below. By push­ing a draw upwards, a slide is brought in front of the lens­es. A sub­se­quent move­ment presents the next image while the pre­vi­ous slide is pushed to the rear.
A vari­ant of the Apés­cope was avail­able with a stand, allow­ing the device to func­tion as a table­top viewer.
