Oswald Boelcke was one of the greatest of the German aces. He had forty confirmed victories at the time he was killed in late-October 1916. Had he survived into 1917 when better German aircraft became available (especially into “Bloody April”), I cannot even begin to imagine what his score could have been. This card shows Boelcke in his classic pose, with his right hand on his hip. He is often seen in informal photos standing like this. The postcard has been removed from a photo album.
