ANS in pencil signed “Edison,” one lightly lined page, 5 x 8, dated in another hand 1926. Edison writes to [Jaffrey P.] Buchanan, manager of Edison’s Record Disc Division. In full: “Just saw a mould truck going over to 24. Thus—Big wheels not touching, except one side or the other. Seems to me the relation between the big & little wheels are wrong at the floor line.” Edison has added a sketch of the truck in question, and has also made a few sketches on the reverse. Intersecting folds, light uniform toning, mild soiling and handling wear, and signature somewhat cramped at bottom edge, otherwise fine condition. R&R COA.
