Substantive Farbstoffe auf loser Baumwolle = Colorants substantifs sur coton en bourre = Direct colours on loose cotton
A trade sample book of direct dyes for loose cotton, issued in 1900 at Frankfurt am Main by the Chemische Fabrik Griesheim-Elektron for dyers and textile buyers. Its pages are grids of numbered rectangular swatches, each printed as a dyed colour patch beside its product name, showing reds, yellows, browns and near-black shades a designer could use for a palette of dense, flat colour blocks with small labels.
