Soft cover. Condizione: Very Good. Reprint. Reprint of the Fourth edition, soft cover, has a tiny skew to the binding, a short split with a touch of peeling starting to the spine at the head, faint sunning with thin reading creases to the spine and hinges, slight bumps to the spine ends and cover corners, and faint rubbing with a couple tiny spots and smudges to the covers, otherwise a solid Very Good copy.
