Once you should happen to make it to Remscheid, Germany: There is a very good Gerd Arntz permanent exhibition there. It is maintained by his son Peter who can tell a lot about his fathers vita.
His son works with the people who put the site online. The IISG also has a collection of his work here I had assumed Arntz had died long before he did. I found this depiction of the radical movements of the 1960s amusing.
"We can say that politics secretly works towards the production of emergencies." A short article written in response to the 9-11 attacks by the philosopher Giorgio Agamben published in Frankfurter Allgemeine Zeitung [Frankfurt general newspaper] September 20, 2001.
First issue of an irregular workers' bulletin put together by users of the website, libcom.org. This issue focuses on the 2008 pay dispute over sub-inflation pay offers.
I'm sure most of us have used one of his drawings at one point or another
There's a web site dedicated to him.
