Pop-ups & Movable Books

AbeBooks: Pop-ups & Movable Books: The Art of Paper Engineering: Paper engineering is the cutting, gluing and folding of paper to create books and ephemera with pop-ups, pull-tabs, flaps and a variety of other moving parts. Pop-up and moving books are most commonly associated with children, but some of the earliest movables were academic titles that used the technique to explain anatomy and astronomy.
