Cave Sing is a “star tunnel” book—that is, a book in which four multilayered tunnel sections are connected so that the book, when fully opened, forms a star. The book’s imagery and words center on 19th-century customs, and each tunnel section contains layers with silhouettes, historical facts and quotes, and collages with many different papers. When opened into the star, Cave Sing is 12″ high and 18″ from each star point to the opposite one.
