Zerlegbares Modell des Diesel-Motors
A German technical booklet by engineer Adolf Richter, published in 1910, presenting a cut-away paper model of the Diesel engine for students and mechanics. The title page uses Art Nouveau ornament with sunflowers and a central cartouche, while the second picture is a red line-block plate of an owl with a propeller, a wooden rule and the word DURG on a banner, suggesting a crisp two-colour print approach a designer could borrow for diagrammatic technical graphics.
