This is a B30 AA Big Book softcover. It is the 4.5" x 7" one. It has a slip-on hardcover jacket on it which was introduced years ago, but never quite made it. The book is in good condition with little use, but tanning pages from lack of use and poor storage. But the hardcover jacket is in good condition, although it may have some light soiling. This will fit any standard B30 softcover big book. Please email me with any questions.
