Bau- und Kunstdenkmäler von Westfalen. Im Auftrage des Provinzial-Verbandes der Provinz Westfalen
A volume of the official inventory of architectural and art monuments in Westphalia, compiled by A. Ludorff for the provincial association and issued in Münster from 1897 for architects, archivists and preservation officers. The plates are measured ground plans and site plans drawn in hard line, with walls filled solid black, later additions in diagonal hatching and surrounding ground in ruled stipple — useful as high-contrast abstract shapes, pattern fills and plan diagrams.
