ANS signed “E,” one page both sides, 8.5 x 11, May 11, 1926. Note written at the top of a letter sent to him by F. S. Blinne. Edison writes, in full: "Blinne, We tried Rosin Varnish but daubs got on & dissolved the Reg Varnish (over) & we could not trust our help, with the thick high viscosity of Varnish we use now it don't go deep & I am afraid to try anything." Blinne's letter asks Edison to consider the "possibilities of further improving the surface of our records," suggesting that "it does not seem economical to use expensive varnish as a basic coat or foundation." In fine condition, with some creasing. Edison carefully controlled the processes in his factories and laboratories, and had famously introduced the 'Edison Diamond Disc Record' in 1912.
