Acid dyes for worsted piece-goods.
A dye manufacturer's sample book from the National Aniline and Chemical Company of New York, issued for textile mills and dyers working with worsted wool piece goods. The pictures are rows of blue and navy dyed swatches with wavy-edged cut-outs, plus a single pen-and-ink street view of a tall office block with horse-drawn carriages, useful for a designer studying colour gradations or a monochrome urban sketch.
