Query: Great pictures and behind-the-scenes info

Besides the complete script and some wonderful production photos, what makes this edition so special are Mel Brooks' "hand written" notes off to the side. Inserted throughout the text, they tell great behind-the-scenes anecdotes about lines that were cut or revised out-of-town, things that happened in rehearsal, and the show's evolution from film to stage musical.
