Excellent. Clean pages. Tight binding. No spine creases. No writing. Outer page edges has a mark which did not go onto the inside of the pages. A few pages have a small fold where it bumped against something, very minor. See pictures for overall condition. About those last three pictures.... This book contains several pictures, and some use color. Reading Amazon reviews, someone mentions theirs being marked up with red ink and shows this same page. I'm convinced this is an intentional printing and not someone just writing. If you compare my picture to theirs, the shapes are thd same. And another mentions a text faux pas. And, this chapter evolves in a way I also feel this is intentional. So, just showing the same pages so you can draw your own conclusion as you read it and unfold part of the mystery.
