An amateur (or perhaps famous) stereo photographer takes us traveling through 1931 with a group of his fellow adventurers.

This latest group of additions includes plastic, wood, metal, and cardboard vintage stereoscopes, covers glass, tissue, standard, and miniature card formats, and spans almost 100 years from the 1860s to the 1950s.

We’ve skipped a few months of collection updates but are making up for it with a nice selection of rarities. Most are completely new to our collection while a couple are only new to the website.

These unknown theater children are first up in Stereoview Spotlight, a new series of posts where we highlight interesting stereoviews in our collection.

We have a bunch of wooden handhelds threatening to walk out if we don’t feature them. We’ve also added a couple of rare metal viewers.

We finally found a filmstrip viewer that has eluded us for years! Plus, you may be shocked to learn that three View-Masters made it into our collection in the past 2 months — we certainly were!

With this month’s group of unique stereoscope designs, we’re almost positive there will be at least one you’ve never seen or heard of.

If this group of vintage 3D viewers doesn’t demonstrate the longevity and variety of stereoscope design, we don’t know what does!

All the new additions to our website are from the 1910s-40s. Two are military-related and two are lookalikes.

Explore our sub-collection of vintage anaglyph brochures, promotions, postcards, and more from the 1920s through the 1960s.

In the past two months, we’ve added a couple of true rarities! Moreover, we’ve built up our Corte-Scope sub-collection with two new additions and increased our NPG sub-collection with 15 new additions.
