I took photos for a couple of articles in a recent issue of 'Guitar Aficionado Magaizine,' (Vol. 7, No. 1). The first article is about an extremely rare (1 of 10 in existence) custom 1938 Gibson Super Jumbo acoustic guitar. These guitars were mostly owned by singing cowboys, including Gene Autry, Roy Rogers and Tex Ritter. The large body size of the guitar led to an increased volume, which I am sure is helpful when performing for a large audience.
The whereabouts of 9 of the 10 were previously known, but the 10th recently resurfaced in Cornelius, OR. The original owner was Peggy Eames, best know as a cast member in "Our Gang" short films in the 1920s, and later toured the vaudeville circuit as a guitarist/singer. The guitar is currently owned by her son.
