Die Kunstsammlungen der staatlichen Kunstakademie zu Düsseldorf
A 1928 Düsseldorf catalogue of the art collections of the state art academy, written by art historian Richard Klapheck and published by M. Strucken, aimed at scholars and collectors of European art. The four plates show a drawn head study in soft grey tones, a chalk portrait of a man in a buttoned doublet, a classical painting of a seated figure before a temple with a crowd, and a carved marble medallion of a wigged man in armour. A designer could take from them the soft tonal shading of graphite and chalk, and the Baroque curled wigs and drapery as period costume references.
