Harald work wasn’t appreciated by many, including the Swiss authorities and was apprehended in June ‘79, after he returned to one of his works after leaving his glasses there. Before his court case he fled to Germany where he continued his work. He was eventually and reluctantly extradited by Germany after he tried to flee to Denmark and served his jail sentence. During this time a petition was set up to free him.

Now days, his work is regarded by many as great art in both Germany and Switzerland. The authorities have restored many of his surviving works. Converting it from an unofficial to and official tourist attraction. So much so that when the building (University of Zurich) where Undine (seen above) was painted upon was renovated. The work was considered sufficiently valuable to cover it and protect int throughout the works.

Naegeli’s graffiti represents a political statement against the increasing anonymity in the city of Zurich. Naegeli was invited to spray paint his work in Germany by the Mayor of Osnabruck but he decided not to because he “didn’t work on commission.”
