[Machine Translation] Ryo Yoshida is a pioneer of spherical-jointed dolls, an author, and a photographer who has worked on the doll photographs of Kayan Amano. The dolls are designed to be opened over and over again, and the back of the doll has a holographic back (with a wide-open garden). In consideration of the fact that the book can be opened over and over again, a hollow back (the kind used in books such as Kojien) was adopted for the spine. The paper is also selected for its eye-friendly tone, and the contents are uncompromising as an educational material and an art book. The book contains numerous photographs of dolls that emphasize the "documentary nature" of the book, which has never been published before. The book also includes a seasonal gravure of Yoshida's works, and at the end of the book is a list of stores where you can purchase hard-to-find doll-related materials. This is a long-awaited book for doll fans and those who aspire to create dolls and human figures.
