Hans Hohlwein Oberurseler Umlaufmotor. Exceptional poster by top artist features German officers conferring as they stand in front of a Fokker E111 monoplane. The Fokker entered service on the western front in 1915. It was distinguished by its outsized propeller, exposed radial engine and the intricate network of steel wires stiffening the single wing. Great rarity, slight evidence of a horizontal fold. 35×29 conservation backed.
