Thomas Alva Edison Three Typed Letters. Signed, "Thos. A. Edison." Each letter is one page, 10.75"H by 8.25"W (sight size), Edison Laboratory stationery, Orange, N.J. In the first letter, November 12, 1917, Edison laments that the shortage of materials due to the World War has negatively effected the quality of disk records manufactured for his phonograph. Edison's second letter, November 14, 1923, explains the shortage of "grand opera records" and "dramatic actor-singers" offered by the Edison and Victor companies, is due to the lack of popular demand. Edison writes, "The phonograph is purely a lyric instrument and not intended for dramatic music." In the third letter, January 16, 1924, Edison thanks his correspondent for pointing out a "bad defect" in the quality of harp music on Edison records, and assures him that the problem has been resolved. Edison notes, "Â…nearly every instrument has some flaw in it." The letters were written to Arthur J. Mann of New Haven, Connecticut. Included is a carbon copy of a letter Mr. Mann wrote to Edison on January 12, 1924, and a transmittal envelope from Edison to Mann (not associated with any of the framed letters).
