A casebound board book with five spreads, not only does Salina Yoon's colorful art figuratively leap off the page, but it can literally be pulled off the page as well. Each spread is designed to nest a removable flash card. When all four flash cards are removed, they can be reconnected outside of the book to create a four-piece puzzle. Yoon has created a three-in-one reading experience: book, flash card, and puzzle.
