This 1986 book is a beautiful book with fresh pages and great cover and dj. But you can see the webbing where the seam is broken on pages 368/369 as shown in the last pic. 
If someone wants this as a reading copy, I have book tape to repair it with if you wish. Otherwise, the book looked very good to me with fresh, white pages until I went to put the Mylar dust jacket protector on and WAM, there was the broken seam inside at the end of the book. see last pic.
Please email with any questions.
