Anybody remember a DIY instrument called the VibraVox?

Back around 1970 an electronics hobbyist magazine (the name of which escapes me) featured a construction project for an instrument called the VibraVox (or VibroVox; not sure of the spelling).  It was a UJT oscillator using a combination of touch switches (glorified metal drawer knobs) for capacitor range selection and a gearshift-lever-operated pot for pitch changes.  Another touch switch introduced vibrato into the sound (hence the name).  The device had a built-in amp and speaker and was built into a teardrop-shaped wooden base with three table legs.  The magazine cover and intro page of the article featured a blonde happily making music using the newly-constructed instrument.

I used to own a copy of the magazine but have long since lost track of it, and all attempts to find any information on this device on the Web come up empty.  Anyone out there know this article?  If so, any chance of sending me a copy or of posting it?

Thanks for your time.
