Zur beurteilung mittelalterlicher kunstwerke inbezug auf ihre zeitliche und örtliche entstehung.
A German art-historical treatise by Georg Humann, published in Strassburg by J. H. E. Heitz in 1928, on dating and locating medieval artworks. The single picture is an oval woodcut-style print of a winged angel standing on a plinth above a small town skyline, with a monogram on the base, suggesting a designer could draw on its framed oval composition and simple line-based figure work.
