An advertisement appeared in Popular Mechanics of February 1928 (page 230) for an aluminium ‘thing’:
Features of a tenor banjo, a banjo mandolin and the ukulele banjo are combined in a recently introduced instrument which has a metal keyboard [fretboard?] to simplify playing, an aluminum bridge in place of the ordinary wooden one and several other distinctive details. It is strung like a ukulele and is constructed like a banjo. A metal resonator and an adjustable metal tone chamber and head tightener are special features. The calf-skin head is adjusted with a nut. The instrument is said to be very easy to play and produces a wide variety of pleasing tones.
Marginal notes in the magazine indicate that the ‘thing’ was called a Tivolette, and it was distributed by Bee-Jay Products Co at a price of $9.50.
