Poster produced on the occasion of Hanne Darboven’s exhibition Quartett ’88, at Portikus, Frankfurt, 17 March–16 April, 1990. The exhibition was dedicated to four outstanding women of the 20th century: Marie Curie, Rosa Luxemburg, Gertrude Stein, and Virginia Woolf. The significance of their work in the fields of science, politics/society, and art/literature in the context of historico-cultural events taking place at the same time is related to the present. The structure of the work is based on an aesthetic concept developed by Hanne Darboven in the past 20 years, consisting of writing down and writing out temporal sequences of events.
