I vaguely recollect having seen posters for this around town, but I didn't read close enough to realize it was an outdoor exhibition. That said, coming across it by surprise was a happy accident. Zebra conversation translated: "As for me, my father is black and my mother white. ... And for me it's the opposite!"
Many of the cartoons were rather violent in nature, understandable if unsettling. On a pleasant albeit cloudy day in peaceful Switzerland, we were briefly transported to the restive locales we hear and read so much about in the news through the artwork of their citizens. I found myself hoping that wherever they were, these defiant defenders of free speech were all right, and would be able to continue their important work.
