A large concrete panel is the centerpiece of the Chil ean Pavilion. It was one of the first original wall panels produced by the Chilean KPD plant. Donated in 1971 by the Soviet Union to support president Salvador Allende's Democratic Road to Socialism, the factory complex produced prefabricated housing components. This panel has since been the subject of several polit ical and ideological controversies. Allende himself signed the wet concrete, only for his gesture to be lat er covered over by Augusto Pinochet, who hid it be neath a representation of the Virgin and Child framed by two colonial lamp fixtures. By bringing together the voices of former KPD workers, inhabitants of housing built with these elements, and invited au thors, this book tells the history of this panel, thus making a fundamental contribution to the exhibition theme Absorbing Modernity 1914-2014.
