Stock Number: 9386

$695.

FOLDING STEREOSCOPIC VIEWER, French, c. last quarter 19th century, stamped with the maker's monogram and "Breveté S.G.D.G." This lovely stereoscope is made of fine mahogany, and stands 6-3/4" (17 cm) tall when set up. There are two square-cut glass lenses for the eyes, and a notch for the nose. The interior is blackened, and a black cloth separates the two halves. The base has an open slot for insertion of stereo cards or slides, viewable by reflected or transmitted light, and the "lid" can be latched into position to form a hand held stereoscope. The whole apparatus folds in on itself, quite cleverly, with three brass hinges, to form a box only 1-1/2" tall. In fine condition, noting age cracks to the lid and an old chip to the base, this is an ingenious form of portable instrument complete with stereo card.
