First Edition, First Print. The book is in good condition. I don’t know what the staining on the edges are but to be safe I wiped it down with hydrogen peroxide, then froze it in a baggie for four days. I then put it in a container with paper towels, moisture absorbers, and baking soda. It sat in the container for two weeks. It came out looking good. The pictures are from after the cleaning process. I tried to take the pictures so you could see the staining. The edges are very yellowed.
