While his work is not particularly motivated by political messages, there is still a social message it carries. “He presents people with the great works of old masters, drawing his perfect copies at the observers’ feet. Mueller invites his audience to share his fascination with the old masters art, helping them to gain an in depth understanding of the old master’s view of the world.” He is in effect by using a public space to create his works bringing something unique and amazing to people for free. “He paints over large areas of urban public life and gives them a new appearance, thereby challenging the perceptions of passers-by. This allows for the observer to become a part of the new scenery offered. While going about their daily life, people change the painting’s statement just by passing through the scene.” This challenge to the public is inherent in every type of street art. It is asking someone who is in the midst of their daily lives to step outside their routine and observe the world they have come to see as a type of visual white noise with fresh eyes.
