By Lowell Cauffiel. Not one you tend to see as much as others in this author's catalog -- and apparently not so prized by the previous owner that they didn't use it to scribble down directions, but in any case, this is the Alpine Manor/angels of death case.
Pre-Mapquest "freebies" aside, this is in average shape for a used PB -- edgewear, cover creases, page toning, a cracked spine and a couple of torn pages -- but rare-ish, and readable.
