Often considered as unique artworks, Man Ray's original sculptures possibly never existed. They are often only known through the artist's accounts in writing, conversations, or conspicuously dated photographs. In place of these absent signifiers, however, Man Ray created alternative variations on multiples occasions throughout his career, under morphed titles, materials, and in various quantities. These he called 'replicas', 'editions', or 'new originals', depending on their appearance and production method. This book explores how originality was manifested in Man Ray's process of artistic reproduction and multiplication.
