There was some beautiful illustration work that went into Lorenz Oken's 1843 natural history book: 'Oken's Allgemeine Naturgeschichte' at the HAAB website. I particularly like the facial expressions on the reptiles. No doubt a lot of it was derivative work. Great stuff. Thanks again to The Cartoonist for finding it.
