POCKET STEREOSCOPE (Jul, 1933)
POCKET STEREOSCOPE SHOWS VIEWS ON FILM
Gone is the old-fashioned parlor stereoscope of a generation ago, but its counterpart, in modern guise, has just made its appearance. The new pocket-sized form of the instrument, illustrated above, is as small as a pair of opera glasses and uses thirty-five-millimeter motion picture film instead of paper photographs. A shift lever causes the pictures to appear.
