1959 - Rambler All Season Air Conditioning

Though air conditioning was first offered in 1940, it was still rare and expensive by the end of the 1950's. In this presentation, Rambler was making sure their sales people knew not only what the benefits were for the consumer, but also how the system worked, which would prove valuable in truly understanding how revolutionary it was to finally have it available for a reasonable price.
These presentations were delivered on a filmstrip, which the display person would advance manually every time the accompanying 16 inch transcription disc beeped. There were a small number that had embedded FSK signals to advance a system automatically, but those were short-lived, because they weren't as reliable as the manual way.
