This auction is for a set of two reproduction prints of drawings that Rudolph Dopyera submitted to the United States Patent Office on June 29, 1929 for the first Dobro resonator guitar.
Background of the Present Invention
In 1928, John Dopyera left National and introduced an affordable single cone resonator guitar under the Dobro name (representing the Dopyera Brothers; John, Rudy, Louis, Robert, and Emile).
One year later, these drawings were submitted to the United States Patent Office for a 'Stringed Musical Instrument' and on August 16, 1932 a patent was awarded. That same year, the Dopyeras rejoined National to form the National-Dobro company.
Though John Dopyera had patented the tricone resonator guitar in the 1920's, and was the true inventor of the device described in this patent, these drawings were submitted in the name of brother Rudolph to help avoid the possibility of George Beauchamp (John's estranged National partner) or his financial backers from again asserting ownership of his work.
There are two separate patent drawings included in this auction and each will be provided on artist quality, acid-free, 60-pound parchment style paper as shown above.
    
    
    
Prints are 8.5" by 11.0" (21.6 by 27.9 cm) in size and are ready to frame for display.
They are packaged in archive-safe, acid-free sleeves and shipped flat in a stiffened mailer to ensure safe arrival.
