Featuring a title from the Libraries’ pop-up book collection and current exhibition, Paper Engineering: Fold, Pull, Pop & Turn.
Numbers or Roly Poly Numbers is a pop-up version of a leporello (a book that folds out in an accordion-like manner). A small brightly-colored cube is opened by pulling apart one side to reveal a small pop-up figure in a smaller cube. The process continues as ten cubes— each with a number of figures ranging from one to ten— are exposed. Kees Moerbeek, a Dutch paper engineer and maker of many pop-up books, has created a delightful way for young children to discover numbers.
