Stereoscope
1857
Wooden box with flip-top lid, set of eyeholes on either side, turning knobs on opposite sides.

Willie and Tad Lincoln were the envy of their friends when they received this stereoscope (similar to a modern ViewMaster).  They could put special photographic cards into a holder inside and see the image in 3-D.  Favorite images were Niagra Falls and the Taj Mahal.

Walnut wood. H 36 ,W 23.5, D 28 cm
