AbeBooks: Die-cuts To Die For: Books With Holes: "Die-cutting is a printing process for cutting shapes in a material. It allows publishers to insert a ‘window’ into a book’s dust jacket, or a page or pages, or even a slipcase. Die-cuts are commonplace but many are elaborate or particularly eye-catching."
