I love lithographs especially those pertaining to nature. My favorites being those related to coral, jellyfish, anatomy, and wild flowers. So naturally I had to share with you Kunstformen der Natur (Artforms of Nature) - first published in the 19th Century 1899/1904 by artist and more importantly biologist Ernst Haeckel who would later inspire many Art Nouveau artists.



Here are some more that are not by Ernst Haeckel but obviously in similar fashion. I do prefer a cleaner look and less clustered, some of Haeckel's illustrations got a bit too crowded, but that's just me.
