Inscribed to the German dermatologist Alwin Scharlau.
After an almost four-year sojourn to Rome, Hertel was appointed a teacher at the Berlin Academy in 1875, a position he left in 1877 to work as a freelance painter. His work comprises still lifes, landscapes and genre paintings as well as 13 tempera paintings for the Imperial Staircase in the Berlin cathedral.
Small tear in upper margin; a few small creases; postmark on verso slightly showing through. Self-addressed by the collector on the reverse. The Mecklenburg physician Scharlau (b. 1888) assembled a collection of artists' autographs by personal application.
