 NMM 10193.  Guitar by Gibson, Inc., Kalamazoo, 1928

This Style L-O belonged to Alvin H. Benesh (1908-2000), a long-time civil engineer with the Bureau of Public Roads who worked in St. Paul, Minnesota, beginning in 1931, and in Pierre, South Dakota, after 1946. Benesh also served in the Navy on the USS Gallatin ADA 169 in the Pacific Theater from 1944 to 1946. According to his widow, Evelyn, Benesh saved money through his teenage years to purchase this guitar, which he strung left-handed. Preserved with the instrument is Benesh’s sheet music collection of 1930s hits that he played on this guitar. The L-O was an early Gibson flat top guitar, introduced in 1926, as an inexpensive model. Made from mahogany, the lightly constructed model was marketed to both Spanish- and Hawaiian-style guitarists.
