(Not my work! These are by André Marie Constant Duméril.)
I really liked the illustrations from this on the Biodiversity Heritage Library, and figured I'd isolate them from the rest of the book and stick them together in a neat lil PDF as a resource for artists - inspiration for beast anatomy, collage, cut-out animation, something to sketch from.
The last four pages are less fun, but I just included them anyway. In the attached PDF, they're scaled down to match the size of the other scans, but they're higher res in the images above.
More info on the book here.
