This book is a collection of Japanese erotic arts called Shunga. List of Utagawa Kuniyoshi, Kikugawa Eizan, Tomioka Eisen, Osaka school, Hishikawa school, Tosa school, and Others.
A good selection of Ukiyo-e erotic art from Japan, but without history, context or details on the artists, nor, for half of the book, even attribution of the artists. The value of the collection is solely as a quick reference to examples of the art.
