Just checking here, so this is a pay service that lets you download the pdf?
I wouldn't mind doing that, as it's hard to find this book, I'm just making sure.
It is a pay site to access various uploaded documents. This book appears to be the French one that Master Minoru had published. I don't know if it is a translation of his one in Japanese. The preview looks as if it were photocopied/scanned. That is fine of course but it doesn't appear to be a clean/ebook quality. Please let me know (you can do it via PM) how it looks if you do end up downloading it.
