Unconcealed describes the emergence of Conceptual art in Europe through the growth of an international network of artists, dealers, museum curators, collectors and critics. The publication is a detailed account of the decade 196 77. The relationships, support structures and strategies of dealer galleries such as Konrad Fischer, Wide White Space and Lisson Gallery to promote artists such as Marcel Broodthaers, Richard Long and Lawrence Weiner, are revealed. The central section of the book brings to life many of the important figures of the art world of this period with a selection of Jacques Charlier's Vernissage des Expositions photographs from 1974 75 that were first shown at the Palais des Beaux-Arts, Brussels in 1975.Previously unpublished data recording the exhibitions and sales of Conceptual artworks to galleries, public institutions and private collections is a major feature of the book. For example, Richard has gathered data from the archives of leading European museums, charting purchases of international artists from dealers to museums, highlighting the power of these relationships. Richard also conducted interviews with dealers, curators, artists and collectors of the period which further highlights the importance of the relationships brought to light in Unconcealed.
