A virtuoso display of Auer's process, with over 40 separate nature-printed objects, including flowering plants, fossil with fish skeleton, bat wing, snake skin, leaves, fern, mosses, algae, laces, wood grain, minerals, on heavy paper in various colors. Many of the plates were printed a la poupeé in more than one color. (Most of Auer's nature printing was monochrome.)
Title translates "The Discovery of the Natural Printing-Process, an Invention for creating by means of the Original itself--in a swift and simple manner--plates for printing copies...containing the most delicate profundities or elevations as not to be detected by the human eye...." Double column text in German, English, Italian, & French. Auer describes his invention and development of this process. He presents his case as the inventor of nature-printing--as opposed to Kyhl of Copenhagen or Henry Bradbury in England.
