Trapezoidal stereoscopic viewer with curved mahogany edges.
 Stereo sold complete with an "Underwood & Underwood" card entitled "The Pillow Fight"
 The stereoscope is suitable for viewing stereoscopic paper and glass plates measuring 8.5 x 17.
 The lenses are in excellent condition and the viewer works perfectly.
 At the front, two adjustable converging lens eyepieces with a ogee and pinion mechanism. On the opposite side of the lenses is a frosted glass plate to diffuse the light for viewing the glass plates; above it, a mirror to reflect the light for illuminating the cardboard plates.
