These 20 Zane Grey books come in a large variety of conditions. 

Most have all their pages still firmly bound, but the binding is breaking down and some pages are loose in the book "Twin Sombreros". One page (the first page) of "The Light of Western Stars" is loose as well. "Fighting Caravans" has one loose page.

Despite the above listed loose pages, all pages appear to be accounted for in every book. 

There is writing and/or book plates in the first few pages of most of these books. For some books, all the writing is just info from previous owners, but others appear to have extensive notes on the books themselves. A few of the books have writing at the end as well. Besides those instances, there isn't any other writing or markings in the books.

One book, "The Up Trail" comes with it's original dust jacket, however it is in multiple pieces and is inside of the book. Many of the other books have part of their dust jackets (the book summary) pasted into the inside front cover. A few books have relevant pictures and other items also pasted into the first few pages. 

All books are hardcovers. Some are in much better condition than others. All pages seem to be accounted for in every book. Three books have at least one loose page. Books show their age and have clearly been read over and over again. Shelf wear varies between volumes.
