Dolk Lundgren is a Norwegian artist who's known for his simple graffiti style that drives messages that go much deeper.
His use of minimalist designs enhance this by making for pieces that are instantly eye-catching and understandable -- allowing his work to be spotted from great distances away. His subjects vary, however many target political and social issues alike. He generates a dialogue surrounding these subjects by supplying his simple graffiti with humorously dark meanings.
Examples of his work includes an inmate in a vintage striped uniform who is throwing the ball and chain that prevents him from escaping like a shot put, while another depicts a runner about to break a finish line that's actually police tape.
