Reproduction-A genuinely Artistic TechniqueSince the late 1990s, Michael Riedel (b.1972) has devised a creative production of seemingly inexhaustible variability in which new works are developed out of existing materials.Muster des Kunstsystems [wallpapers] is a collection of nineteen removable pattern sheets. The patterns shown (all untitled) were created between 2010 and 2017 and applied to gallery and museum walls as well as canvases and other support media.Besides other places, they were on view in exhibitions at the Schirn Kunsthalle, Frankfurt; the Palais de Tokyo, Paris; the Museum für Angewandte Kunst, Vienna; Kunsthalle Zürich; the David Zwirner showrooms in London and New York.The texts of which the patterns are composed are self-descriptions of the art system that the artist excerpts from and then reinserts into the flow of communication.
