Some also call this diminutive banjo a "ukujo". I own 2 from the 1930's-1940's, as well as a banjo-mandolin, and some other full-size 4- and 5- string banjos. Ukes and banjos are two musical instruments to have originated in the United States, and so have value and interest for instrument collectors. The best collections of rare and important ukuleles is in Japan. Go figure.
