Adolph Bayersdorfers Leben und Schriften
A 1908 Munich biography by Hans Mackowsky of the art historian Adolph Bayersdorfer, published by F. Bruckmann and illustrated with photogravure portraits of its subject. Its two pictures are sober studio portraits of a bearded man with a moustache, one a tonal etching-like head in a fur-collared coat, the other a seated three-quarter figure in spectacles holding a small object, both rendered in soft grey and brown tones that suggest a restrained, documentary style for period biography covers or sepia-toned editorial features.
