Otto DIX (1891-1961), German expressionist painter. Autograph letter signed to the German publisher Bärenreiter, Kassel. ½ p. in-4. Otto Dix tells his publisher that the title of the drawing is wrong: "Barenreiter Verlag Kassel P.P. das Blatt heisst nicht Bauernking sondern "Bettina". Es ist mein Enkelkind Bettina [...]". [The plate is not called La Fille de la campagne, but Bettina. Bettina is my little girl]. He asked for 200 copies to be sent to him on cards. When his daughter Nelly died in 1955, Otto Dix adopted Bettina.
