Indanthren Dyeings on Rayon (Viscose) Yarn
A dye-house sample book issued in 1920 by the General Dyestuff Corporation to show textile mills the Indanthren range applied to viscose rayon yarn. Pages carry actual yarn skeins tied into small bows, mounted in columns beside letterpress dye names, weights and process codes, giving flat color chips, glossy fiber texture and a rigid two-column grid with numbered margins.
