First edition Stephen King The Dark Half Hardcover

First edition hardcover book of Stephen King's The Dark Half. Read once and kept protected and appears to be like new. Great gift idea for a SK book lover. How to identify the first edition of the Dark Half: "First published in 1989 by Viking Penguin" on CP "1 3 5 7 9 10 8 6 4 2" on CP. CP=copyright page. From https://stephenking.com/other/identifying_first_editions.pdf. I have first editions in other titles. Also, later edition hardcovers in other titles. Please ask, if interested. From stephenking.com website, "For years, Thad Beaumont has been writing books under the pseudonym George Stark. When a journalist threatens to expose Beaumont's pen name, the author decides to go public first, killing off his pseudonym. Stark isn't content to be dispatched that easily, though. Beaumont's alter ego comes to life and begins to stalk those responsible for his demise. The police suspect Beaumont is responsible for these violent crimes."
