ALS in German, one page, 5.25 x 8.5, October 23, no year. Untranslated letter to "Herr Fritzsche," presumably his publisher, to whom he returns proof sheets, and agrees to certain proposals concerning the latter. In very good to fine condition, with scattered light creasing, splitting along intersecting folds, and a light block of toning from prior display; second integral page detached but present.
