At Princeton University, portraits of blue-collar campus workers are now taking center stage. A new set of paintings are offering a fresh perspective on the working class, racial struggle and empowerment at the Ivy league school. Mario Moore, the artist behind the paintings, views his artwork as more than just decoration. By showcasing the university's workers, he wants to pay tribute to them and "put them in positions of power," he told CNN. Moore painted 10 workers at Princeton, including people in facilities, dining, grounds maintenance and security. He focused on African-Americans as his subjects and says he was inspired by the plight of migrant black families who have struggled for job opportunities and equal pay. Growing up in Detroit, he remembers his own father working blue-collar jobs to provide for him. "Mario's portraits capture beautifully the character and contributions of valued members of our campus community and bolster our broader efforts to ensure Princeton's portraiture and iconography reflect the University's values and diversity," said university spokesman Ben Chang. "We are excited to acquire some of Mario's works so they become a permanent part of the University's collection and can be appreciated by future generations." Moore, 32, was one of five Hodder Fellows at Princeton. After he completed the program in June, his paintings were displayed at the school's exhibition. The Princeton University Art Museum ... subsequently purchased a lot of his work.
