Yay for pop-up books! There’s an exhibition of pop-up books, also known as movable books, at the Brooklyn Public Library (various branches) going on now through the end of the year. It was curated by The Movable Book Society and there’s a companion book with a Maurice Sendak cover. Lothar Meggendorfer was an important innovator in the history of this art some call “paper engineering”. Here’s another online exhibit about pop-ups. And the Popuplady has special bonus info on her site: how to deodorize a book using kitty litter. Very handy for us used book shoppers.
