'BOOK BOOK' is quite literally a "book about books", an artist book by Bird Pit that takes each physical element of a book as its subject. It covers everything from the cover, spine, and table of contents to the pages themselves, as well as the copyright page, ISBN, and even the distribution and future of books, reinterpreting the medium of the book through the author's distinctive perspective and humour. The book comprises eight chapters, each exploring a book element through the author's distinct lens. A character serving as narrator guides the explanations, while charmingly detailed drawings enhance the reading experience.
