Circa 1980 no other European street artist had more media coverage than Naegeli. His virtuosic spray figures were based on his political agenda. These police photos were used in a trial against him. Naegeli fled to Cologne/Düsseldorf. He continued to spray until sent to prison for 6 months in 1984, despite support from Willy Brandt and Joseph Beuys. Photos: Zurich City Police, 1978–79.
