Der Motorwagen
Der Motorwagen is a German automotive and aeronautical engineering journal issued in Berlin by Krayn from 1898 for the Automobiltechnische Gesellschaft and its successor, addressed to engineers and designers in the motor trade. The plates are plain ink line work: force-vector diagrams with lettered arrows, machine cross-sections, tyre-and-soil sketches, and side elevations of car bodies reduced to outline, useful as ready-made technical schematics and period vehicle silhouettes.
