With more than 9,000 pop-up and movable books in her collection, Ellen G.K. Rubin has earned the nickname of Popuplady. Today, pop-up books are often thought as of strictly for children, but they’ve long been used to instruct adults on mathematics, astronomy, astrology, and medicine. Rubin says she considers herself a cheerleader for paper engineers, the professionals who make movable books come to life. Through her collecting, she’s become an expert resource to those who study this skilled craft.

In the video below, Atlas Obscura takes viewers on a tour of Rubin’s private collection. For more on Rubin and her work, read our recent profile.
