On the back of the letter is a pay order written and signed by Colt for $164.50, payable to Captain John Johnston. The letter is dated January 9, 1836, and the pay order is signed "Sam'l Colt."

Thomas Edison (1847-1931) was arguably one of the most influential people in all of history. Credited with "inventing" the Twentieth century and developing the modern research laboratory, he was the most prolific inventor in history with 1,093 U.S. patents in his name as well as patents in the United Kingdom, France and Germany. His numerous inventions included the electric light bulb, the phonograph and the motion picture camera.

Edison owned numerous companies including Thomas A. Edison, Inc, which oversaw his early recordings. The standard of the day was the phonograph and the phonographic wax cylinder. The cylinder was a tube containing up to 2 minutes recorded music. In 1912, Edison introduced the new Blue Amberol Cylinder. More durable than the previous design, these new cylinders could hold up to 4 minutes of recorded music. Edison's company would continue to sell cylinders until they went out of business in 1929.

This typewritten note, dated May 7, 1921, was composed by Charles Edison, son of Thomas Edison, to his father. It discusses the inefficiency of the Blue Amberol division of Edison's company. The content specifically compares employee Jimmie Carson and his team to the team working on Blue Amberol. Charles determines that the Blue Amberol division is not working to its full potential and suggests that the team manages to make itself look busy when necessary. Thomas Edison has written a personal note at the top, "Charles. This is a rotten dept." and includes his prominent initial, "E."
