Bought from the Penguin Books McGrath foundation as sales contributed to donations of the foundation. The back cover and last third of pages are wavy. The back cover also looks like it was a little damp. However, no typing is affected at all and the book is very readable. Happy to send more photos. One photo of the pages shows how wavy the last third of pages is. The other photo of the pages shows how perfect the first two thirds of the pages are.
