This is a set of 2 books. I read them once or twice, then kept them on a bookshelf and stored them in a dark place. Only Volume 2 is a first edition, and it seems to have a slight sunburn. There are some bent parts on the inner obi (see photo 8). Volume 1 does not have an obi. Otherwise, I think the condition is good. Thank you to those who understand that these are used books.
