There is age-related yellowing. There is a scratch on the top of the spine of the cover. "Closed Room Gathering" has a small crease at the bottom. Otherwise, I think the condition is generally good. I have taken photos to show the condition of the books as much as possible, so please take a look. Please understand that these are used books and consider purchasing them.
