In this groundbreaking book, Osumi Yukie tells the story of more than five decades' engagement with metal art, introducing us to her creative world from the perspective of Holder of an Intangible Cultural Property, an official title popularly known as "Living National Treasure." Osumi has been exceptionally active as a cultural ambassador, not only lecturing, exhibiting, and demonstrating in Europe and the United States, but also using her role as a female creative leader to communicate with women globally, encouraging them to follow her example and make their mark in the world of art. Her diligent study and profound understanding of many different metals and metal alloys empowers her to give them a feeling of softness and warmth, exploiting these unexpected properties to create colorful mindscapes that transform the characteristics of her chosen medium. We at Onishi Gallery feel that it is our duty and pleasure to communicate our excitement about this uniquely beautiful medium to connoisseurs in the United States. We are therefore especially proud and delighted to represent Osumi Yukie, a pioneering woman whose skill and dedication open up exciting possibilities not just for metalwork but also for the wider world of art.
