Number 90: The Challenge of a New Shigeo Nagashima - Masaharu Shingu (Showa 50, First Edition) Shigeo Nagashima Published about 50 years ago, so there is some yellowing, but the pages have no folds, reading marks, or stains. Due to the age of the publication, I believe there are not many copies of this book remaining. Regarding the contents, I have included photos of the table of contents. Please take a look there. The photo of Mr. Nagashima on the back cover is cool. Please understand that this is a vintage used book before purchasing.
