&gt; A project for public space, with posters put up in Karlsruhe, Cologne and elsewhere in autumn and winter 2015&#x2F;16<p>&gt; Commissioned by ZKM | Center for Art and Media Karlsruhe on the occasion of the exhibition Global Control and Censorship, October 4, 2015 – May 1, 2016. The Cologne part of the project consists of 200 advertising columns<p>If you click the link &quot;Advertising Columns&quot; you can see those.  I guess I am still confused as to what calling the number does (that we can actually see) and how it relates to the art.
