I've discovered a new Naturalist:
Ernest Haeckel. Based on the limited number of images I've seen of his so far, he seems a bit more obsessive and
alien than ol' JJ Audobon. The picture here is a detail from a
glorious print of trilobytes and other chelicerata.
This page has a huge TIFF of the full image that you can download and make your own poster from...
Furthermore, I've also found a
massive collection of Naturalist images - it
is a commerce site, so the previews are watermarked, but they're very large and very beautiful. I may even buy one of these prints.
