A 1930 article from The Melliand on vicuna wool, covering the animal's Andean habitat, its hunting and near extinction, and the physical properties of its wool and beard hairs. Most of the text is a microscopic study of the fibers, with fineness measurements and diameter-distribution charts that compare vicuna with camel hair and llama. It ends with a short section on the fabrics made from vicuna (blankets, velours, hats).
