By the President's Commission. "The Official Complete & Unabridged Edition" from St. Martin's Press. The text is less dense than in contemporary editions, but the result is a doorstop of a book; pick your poison.
If you've never read the WR, this is a solid (…very!) copy to have in your library. Some shelfwear, a small crease to the front cover; some mild page toning inside; otherwise clean, neat, sits straight. Will also brace windows and furniture with ease ;). A fine reading or research copy.
