Set of two books: "The Power of Books" and "Study Methods for Those Over 50." - Title: The Power of Books - Author: Hideo Takahashi - Title: Study Methods for Those Over 50 - Author: Fuyu Tōmon These are recycled library books. They have "recycled material," "discarded," "withdrawn" stickers and stamps. Therefore, they are categorized as "slightly damaged."
