Säurefarbstoffe im Druck auf Wolle = Colorants acides dans l'impression sur laine = Acid colours for wool printing = Coloranti acidi nella stampa della lana
A Sandoz trade sample book of acid dyes for printing on wool, published in Basel around 1900 in German, French, English and Italian for textile colourists and dyers. The pictures are swatches of striped wool fabric in deep blue and black dyed against cream undyed stripes, with German and French captions naming each shade, so a designer can read colour value and stripe rhythm directly from the samples.
