This is a set of two educational books featuring lectures by Professor Yoshio Higashii. The obi (sleeve) reads, "The immortal lectures of Professor Yoshio Higashii, known as the Pestalozzi of Japan." I read them once, having been introduced to them by a teacher I respect. I am offering them for sale in the hope that someone else will find them valuable. They appear to be in good condition with no signs of use, but please consider that they have been stored personally.
