I generally avoid lift-the-flap books in the library, just like I avoid pop-up books, because they’re not likely to have a long life.  So that is already one mark against getting a recommendation, and in addition, this has a very limited audience: strictly preK-K.  Each page has a Who __________? question (e.g. “Who wears a carrot for a nose?” with the answer revealed when the reader unfolds either the top or bottom half of the page.  The illustrations are cute, and it’s kind of fun to see how some of them shift with the unfolding of the flap, so that saves the book from an NR rating, but the best I can do is to call it an “Additional Purchase.”
