You're absolutely correct - not all these images really match the title. These are just the ones that caught my eye from a large collection available at an old Arizona State University website.
This is an excellent set of illustrations. Excellent. There is even an outline of the publishing history and short review of each author and their work. This may be a few years old and I'm sure I've seen some of the images previously but this one is worth recirculating periodically, even if it is known around the traps.
