This is the detail from the cover of Richard Knoller's (professor at the Technischen Hochschule in Vienna) Ueber Laengsstabilitaet der Drachenflugzeuge, published in 1911. In real the image is only about an two inches wide and spare-but-detailoed, wisely placed in the center of the oversized pamphlet, and set in a lofty blank space. Brilliant.
