Here’s an interesting image of an old advertisement for ukulele lessons from The Hawaiian Institute of Music:
The text reads:
ALWAYS the life of the party, the center of attraction, is the girl with the Ukulele. Whether you choose the native melodies of the “Paradise of the Pacific” or the latest songs from Broadway, this fascinating little instrument lends them a haunting sweetness that lingers in the memory.
We guarantee to teach you to play in 20 scientifically simple lessons, sent by mail.
