Stephen Biesty's Incredible Cross-Sections
by Stephen Biesty, Richard Platt
I was so very obsessed with this book as a kid. Oddly, one of the parts I remember most vividly was checking out what all the little people were doing. And the soldier whose intestines were hanging out in the tank cross section, of course. Biesty really knows how to appeal to kids.
I'd love to reread this as an adult.
