This French stereo viewer includes two eye lenses built into the side of a wooden box.  The rear surface of the box is a frosted glass plate, positioned at the focal point of the lenses.  A transparent stereo image card is placed in a slot near the frosted glass plate.  The stereo image is illuminated through the plate and by a hinged mirror on the top of the box.  The user would face a light source (such as the sun) and adjust the mirror to illuminate the card.
