I believe this book was purchased around 1950 as an Iwanami Shinsho. It's a fascinating book, vividly written with the ideas and expressions of the time. Being from that era, it shows signs of aging throughout. There's a library stamp on the first page (see photo 9). Please purchase only if you understand and accept this. Please check the photos carefully and make your purchase only if you are satisfied. *The book is at my grandfather's house, which is far away, so the shipping date is undecided. I will contact you as soon as it's determined. m(__)m
