käpt'n kalle sees himself as a self-authorized artist of the public space.in 2013, the artistic campaign in the public space began. the artist intervenes self-authorized in the public space and spreads the signet of a sailor. his work deals with the meaning of life, the question of who owns the public space and who is allowed to intervene in it. surveillance is also part of his argument. besides the photo documentation, the analog art in public space, screen prints and other works, there is now a whole series of digital works in the form of gifs based on the photographs.
