This book explores the influential work of a husband and wife team in the international photography scene, noted for their blend of topographical documentation and conceptual art. It highlights their impact not only through their own creations but also indirectly via protégés like Thomas Struth and Andreas Gursky. The book focuses primarily on "Framework Houses," their first publication from 1977, which had been out of print until reproduced by MIT Press. The publication includes 350 duotone illustrations and offers insights into their creative approach, which significantly shaped contemporary photography discourse.
