In & Out of Amsterdam presents more than 120 works—including works on paper, installations, films, and photographs— by artists who were part of this remarkable creative culture, including Bas Jan Ader, Stanley Brouwn, Jan Dibbets, Ger van Elk, Hanne Darboven, Gilbert & George, Sol LeWitt, Charlotte Posenenske, Alan Ruppersberg and Lawrence Weiner. Essays by an array of scholars, accompanied by lively illustrations and documentary photographs, illuminate their significance as well as the unprecedented role that prints, bulletins, posters, mail art, artists' books, and other ephemera played in the artists' discourse.
