This must be a movie gag. But the film isn't out yet.... unless it was a book first -- then it would be a reference gag to the book. But if you didn't read the book, if there is a book, you won't get it until you see the film, which isn't out yet.
i saw the movie early at a film fest and this is easily the vagueust possible reference to it. the little girl's name is olive, but besides that this design doesn't seem to have much to do with the film.
