Stereo King 3D Viewer, Model HN 44

Japan, 1950s

This powder-blue plastic viewer was produced by Nippon Stereo Photo, Ltd. It’s a basic, lightweight viewer with no ability to make viewing adjustments but has a cool & curvy Art Deco design on top. This viewer also comes in black and we’ve seen it come with scenic slides packaged in envelopes that say “Tokyo Stereo Photo, Ltd” and slide mounts with “Nippon Ace Vue Stereo” printed on them. It’s not clear how those 2 companies are related to Nippon Stereo Photo, Ltd, which is printed on this viewer’s box.
