Woll- und Halbwoll- Farbstoffe = Colorants pour laine et mi-laine
A dye manufacturer's sample catalogue from 1900, published in Hoechst am Main by Farbwerke vorm. Meister Lucius & Brüning, showing wool and half-wool colorants in German and French for dyers and textile trades. The first picture shows swatches of dark navy blue fabric labelled with product codes, and the second shows an engraved bird's-eye view of a dense industrial town or factory complex with rail lines, useful for designers wanting crisp dyed-cloth samples or dense engraved cityscape detail.
