One interesting thing I've noticed is that not all of Tenniel's illustrations are rectangular. Scattered through the books are a handful of L-shaped images, like so:
Obviously these images are meant to have the text flow around them and fill in the white space, as in this edition here:
But I've also seen editions in which, evidently out of carelessness, these same illustrations were treated as rectangular, and the page was left with a big empty expanse. Shame on the typesetter, I say.
