An AV Survivor

Shown here is a ca1930 Balopticon "magic lantern," a projector for the glass slides then in use (35mm slides weren't developed till the latter 1930s, and not widely used till after WWII.) This machine was part of the school's audio-visual equipment, along with a large collection of glass slides, covering the different countries of the world, famous artworks etc. We still have not only several projectors, but a wooden cabinet with thousands of slides!
