The publication Mobil, autonom, vernetzt, Kritik und ökonomische Innovation in Ephemera der Konzeptkunst, 1966–1975 deals with the advertisements and exhibition announcements printed by Jan Dibbets, Adrian Piper, Daniel Buren and Eleanor Antin between 1966 and 1975. These ephemera—simultaneously works of art, advertising instruments, and documentations for artistic actions—are exemplary for the communication-based, flexible, and mobile practice of conceptual art. A 2015 interview with Barbara Preisig discussing ephemera can be found here.
