Katechismus der Spinnerei, Weberei und Appretur, oder, Lehre von der mechanischen Verarbeitung der Gegespinstfasern
A German technical catechism of 1890 by Albert Ganswindt, published in Leipzig by J.J. Weber, teaching spinning, weaving and finishing of textile fibres to students and mill workers. The pictures are black-and-white line engravings of machines, some rotated sideways on the page, with numbered figure captions; a designer could take their crisp hatching and mechanical diagram style for industrial or heritage graphics.
