Wissenschaftliche Messinstrumente für Anthropologie nach Prof. Dr. Rud. Martin und für Orthopädie nach Dr. Wilhelm Schulthess
A 1911 Zürich catalogue by the firm P. Hermann presenting scientific measuring instruments for anthropology, designed by Rudolf Martin, and for orthopaedics, designed by Wilhelm Schulthess, aimed at researchers and clinicians. The pictures are plain black-and-white or sepia drawings of single instruments such as protractor-based calipers, a graduated arc gauge and a bone-measuring stand, shown isolated against dark or pale backgrounds with crisp outlines and numbered scales, useful to a designer seeking clean technical diagram styling.
