Even if your interest in the bird eggs of Germany and neighboring countries is close or equal to zero, there's enough artistic merit in these hand-colored engravings by JF Naumann, a self-taught engraver and etcher who co-founded the German Ornithological Society in 1850, to take a peek. The arrangement of the eggs is really the striking part, though some of the individual shell patterns are lovely.
These ten plates are collected from the five-volume Bird Eggs from Germany and Neighbouring Countries - Described and Illustrated, published in 1818. See them all on BibliOdyssey. Link
