Lichtechte Direktfarbstoffe auf Baumwollstück = Colorants directs solides à la lumière sur tissu de coton
A colour sample card issued by the Sandoz chemical works of Basel, Switzerland, around 1900, showing direct dyes fast to light on cotton cloth, with text in German, French and English for trade buyers. The three plates are grids of numbered swatches in yellow, orange, red, blue, green, purple and brown, each shown in a light and a dark tint, giving a designer a reference for dye shades on fabric.
