For the first unit in the course, we are reading the Grimm Brothers fairy tales edition illustrated by Walter Crane - so of course I had to say something about Walter Crane's BEAUTIFUL edition of Aesop's fables - the Baby's Own Aesop of 1887. He took limericks W.J. Linton and built full-page illustrations around the limericks, sometimes one on a page and sometimes in fascinating combinations. You can find the book online at the International Children's Digital Library, along with other books illustrated by the amazing Walter Crane.
Here is a Flickr slideshow of images from the book:
