Stereo Dia 2x2 Viewer

Hungary, 1950s

The odd, patched-together appearance of this viewer — with what looks like popsicle sticks taped onto it — seems more like an early prototype rather than a finished product. However, the picture on the box shows the same popsicle stick-ish design. Each side of the viewer is marked with sticky dot — blue on the left side, yellow on the right side. The colors correspond to the colors on the 2x2 slides, indicating which side of the viewer the slide should be placed. The set comes with a 6 numbered slide pairs, dark blue on one side and white on the other. The slides are inserted with the dark blue side facing the viewer.
