Martin Kippenberger “When It Starts Dripping From The Ceiling” / accidentally scrubbed clean

(In 2011, Kippenberger’s work - a wooden structure with a rubber trough painted to look as though it had once contained a puddle of dirty rainwater - was on view at Germany’s Ostwall Museum. An overnight cleaner mistook the trough’s hand-painted patina for simple dirt and scrubbed it away.)
