Kunihiro Nagano - Beauty secret museum - 1992

This is a book about the art of Shibari, also called Kinbaku, which is a Japanese style of bondage that involves tying according to certain technical and aesthetic principles, using cords generally made of natural fibers. There are several models and the lower lips are censored.
The bottom part of the book is a bit dirty, as you can see in the last photograph, otherwise it is in good condition.
