I received this from someone else. As this book was published in 1985, there is yellowing due to age, but it does not affect readability. There are no tears, writing, or folds, but due to the yellowing, I have categorized it as "slightly scratched or dirty." As it is rarely available and difficult to obtain, I purchased it for 2400 yen plus shipping. Please understand that this is a used book. #NomuraSecurities
