Flat SIGNED to the title page by both Mr. Hilts and Mr. Day. Like new, appears unread, interior is clean and solid. White laminate wraps (softcover) are remarkably clean with the odd smudge or small stain, just a hint of "corner curl", hint of shelf wear. Thorough and well illustrated with photographs. Laid in is an explation of Rockwood buildings depicted on the front cover of the book.
