Clavioline, an Uncommon card

The card carries these facts from its Wikipedia article.

• The instrument consists of a keyboard and a separate amplifier and speaker unit.
• The keyboard usually covered three octaves, and had a number of switches to alter the tone of the sound produced, add vibrato, and provide other effects.
• The Clavioline used a vacuum tube oscillator to produce a buzzy waveform, almost a square wave, which could then be altered using high-pass and low-pass filtering, as well as the vibrato.
