The old “Art Pen” ink is no longer available: a slap in the face for every cartoonist. Stephan Katz boxed clever however: when he heard Weimar’s famous Anna Amalia Library was burning, he grabbed all the jars, pans, bowls and yoghurt pots he could lay his hands on and rushed to Weimar to catch as much hose pipe water dripping from the library as possible. He mused that this water was enriched by printing ink from the works of old masters like Wieland, Goldt, Goethe and whoever else might have been there. At home, he condensed the water and was soon the proud owner of the most exquisite ink, which could have been used for the drawings on display in this very product – in theory, anyway.
