Ecypa vegetabilium usibus medicis praecipue destinatorum et in pharmacopolis obviorum variisque modis praeparatorum ad naturae similitudinem expressa.

Halle & Leipzig 1769. Folio. 200 nature-printed plates in colour. Modern calf with six raised bands. Gilt spine. Plates only, lacking title and text. A rare nature-printed book. The plant itself was used, instead of woodblock or engraved copperplate. After the specimens were arranged, they were covered with dark dust, and the outlines thus formed on the paper were coloured by hand.
