A detailed account of a decade of artistic activity is accompanied by an extensive set of previously unpublished data, charting the exhibitions and sales of Conceptual works to galleries, public institutions and private collections. 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 and make fascinating reading. Including numerous interviews with key figures of the period, Unconcealed exposes the new dealing, curatorial, collecting and teaching methods formed in this decade that continue to be critical to today’s art world.
