April 23rd, 1896 Edison United Phonograph Company, Mills Building, New York City Dear Sirs:- I desire to take out patents on my new mailing box for Phonograms in England, Germany, France, Belgium, Italy, India, Austria, Queensland, Victoria, and New South Wales. As the expense attendant upon taking out these patents will be borne by yourselves, I should like to receive from you sufficient authority to instruct my attorneys to commence the work of filing an application. Yours very truly, Thos A. Edison
