Condition is based mostly on age of book. These older books have been read through and show it. The cover is clean, no stains or markings. The corners appear fine but are slightly rounded. The inside pages are lightly browning but are still very readable. There is some spine curl and creases along the spine and on the cover. There are also creases on the back page and at the top and bottom of the book. The cover is slightly off centered. It also has pencil price mark erased on the back left corner (ie 45 cents). I would estimate this to be in the range of FN to VF-. It is not in that bad of shape and does not have all the criteria that makes this a truly FN book. Its readable and something to add to your collection at a cheap price.
A stock picture is shown here. It is shipped well -padded and bagged/backed. I am not a professional grader so this is just my best estimate. Contact me if you have any questions or wish to see some pictures.
