Gibson GB-1 #8540-5
An early 1930s Gibson catalog informed players that the guitar-banjo was "used most effectively in small dance combinations and of especial value where a piano is not available." This 1926 guitar-banjo is one of only ninety such instruments produced according to Gibson historian Joe Spann. The pot conforms to standard style 1 specifications for the period; the maple neck has no volute, or handstop, and the fingerboard has dot inlays typical of the style 1 of this era. The guitar-shaped peghead has no inlay other than the silkscreened "The Gibson" logo. #8540-5 remains in original condition in its #521 case by Geib and Schaefer.
