Elements of Pop-Up: A Pop-Up Book for Aspiring Paper Engineers

After working in the field of pop-up books for years, these two guys knew a lot about the art of paper engineering. They would have conversations as they were designing new books in which one would say to the other, "Why don't you do the "tent-thingie" on that page."
