The first and probably best-known painting is "Zürich Eiszeit" (English: Zurich ice age), which caused a scandal in 1975. It apocalyptically shows, in a photorealistic way, a frozen city of Zürich full of ice and snow: Ice age is loose, sheets of ice lie between old historical buildings. There is even a warship, that got stuck in the ice, and a group of penguins. If you look closely, you will notice the last "penguin" is actually something else... ;~) The work was interpreted as a criticism on the supposedly fossil and cold state of Zurich; a state, that the 1980s movement of youths and writers like Fritz Zorn criticised heavily, too.
