This is a **signed copy of Atsuhiko Nakata's book, "The Textbook of Self-Study: Making Learning Incredibly Fun,"** also known from his YouTube University. Purchased directly from Mr. Nakata's website. After reading it once, it has been stored at home as part of my collection. The obi (paper band) and the top of the book have some tears. The signature is shown in the photo (4th image). Signed copies are very valuable, and I believe this will be a special book for fans. I will ship it within 24 hours so you can read it right away. * Safe and anonymous shipping via Yu-Yu or Raku-Raku * Packaging may use recycled materials * Please refrain from price negotiations * Instant purchase is welcome without comments
