3M Sound Slide

Filed under: Item of the Day — Jason Onerheim @ 12:01 am

A 3M sound slide with image slide and sound disc intact. This one has an image of a group of men, possibly 3M staff, clustered around a piece of machinery. A special slide projector would show the slide and play the audio recorded on the dark gray disk simultaneously. They were made by the 3M visual products division Saint Paul, Minnesota in the 1960s.
