Yes, it’s an ad. But for what? Might just surprise you.
The Internet Archive is a vast repository of still and moving images, text and audio. It’s also the home of the Wayback Machine, enabling visits to websites from years past. The moving image archive has a wide range of content that has found itself in the public domain. The AV Geeks section has many educational films from the latter half of the past century. This particular example is from a 1959 Coronet film. Coronet produced countless films like this one in the 50’s and 60’s. If you’re old enough to remember what an event bringing out the 16mm projector was, you might just enjoy this.
