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.

How have car manufacturers used 3D to advertise? We’ve brought together some examples from our collection.

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.
