ALS signed “Edison,” one page, 5 x 8, no date. The second page of an ALS. In full: “We are on the track of a Lithographic Concern who will probably do the letters for 3 1/2 cents. Expect to hear from them shortly. What is your opinion of this scheme - perhaps we could leave the books for a week at each place and then call for them & thus make a smaller number of books cover a large number of people.” In fine condition, with chip and small separation to lower left corner, a couple of small separations in upper left and faint paper clip impression. R&R COA.
