Möglichst lichtechte Nüancen auf Wollgarn : hergestellt mit sauerziehenden Farbstoffen
A 1930 dye-industry sample book from I.G. Farbenindustrie in Frankfurt am Main, showing wool yarn dyed with acid-fast colourants for designers and dyers to compare shades. The pictures are rows of small wool pompom-like swatches in purples, teal, deep red-black and greens, set against a plain paper ground, useful for palette references of muted, heathered tones.
