Geschichte der Kölner Malerschule, mit 131 Tafeln
A 1923 art-historical volume on the Cologne school of painting, published in Lübeck by B. Nöhring, written by Karl Schaefer with Ludwig Scheibler and Carl Aldenhoven, for scholars of German painting. Its plates are black-and-white photographs of late medieval altarpiece panels, printed rotated on the page, with captions naming the Master of the Holy Kinship and the Master of Saint Severin. Designers can draw on the crowded group compositions, gold-ground architectural framing, and dense procession scenes for historical reference.
