Investor Z, a complete 21-volume set by Norifusa Mita. I bought the entire set, hoping my child could learn about investing through manga from a young age. It was great for both of us to read together. I now need to reduce the number of books on my bookshelf, so I'm putting these up for sale. Rest assured, this is a one-owner set (I purchased them new and have kept them in storage). The condition varies slightly depending on the volume, but they are all in perfectly readable condition. As these are used items, there may be minor stains or scratches. Please consider this before purchasing. *Please refrain from purchasing if you are concerned about minor imperfections. - Title: Investor Z - Volumes: Complete 21-volume set - Author: Norifusa Mita Recommended for those who want to learn about investing, fans of Mr. Mita's work, or anyone who wants to reread the entire series at once. The end of each manga volume includes investment-related interview articles, making it a compelling read. Thank you for looking.
