As you see here, pop-up books share similar physical qualities to the board books aimed at toddlers.

Pop-up books also share traits with children's picture books. Both rely heavily on illustration and are typically light on story, perhaps a paragraph or two per page. Here's a side-by-side comparison of the art-to-word ratio:
Sabuda, Robert. (2005) Winter's Tale. New York, New York: Little Simon. Van Allsburg, Chris. (1985) The Polar Express. New York, New York: Houghton Mifflin Company. |
Sendak, Maurice, Arthur Yorinks & Matthew Reinhart. (2006) Mommy? China: Michael di Capua Books. |
However, as the art and creativity behind pop-up books grew, so did its audience. Today the book form has fans among both children and adults. It is not difficult to trace that shift in consumption as the constructions became more delicate and elaborate.
