Blue 2: A Pop-up Book for Children of All Ages Book

For a pop-up book, this demands quite a bit of the reader. Its spectacular pop-up structures can be touched, twirled, folded and pulled, all of which may be necessary to find the hidden blue numeral two on each page. The sentences are sometimes nonsensical but full of interesting and complicated words, like "Jubilant Kookiness Laughing". It's a book that works on several levels; it's a complicated puzzle, like a magic eye, a linguistic tongue twister, and an multimodal adventure. This is a book for one (careful) child to explore at his or her leisure. It's appeal is almost entirely visual, but some children might be enticed by the word play as well. The blue twos are hidden cleverly enough that even an observant adult will have to spend some time poking and poring though it.
