This is an old textbook published in 1956. The top, side, and bottom edges are dirty. There is age-related deterioration like in image 4 on the inside front and back cover pages. The photos are smudged (image 5). On page 86, what is the damage below image 6? We plan to send it by post, with measures taken to protect it from rain. We look forward to your purchase if you understand the above. Thank you for looking.
