Photograph of an exterior view of the Student Union building on the campus of the University of Southern California, [s.d.]. The three-story building can be seen at center and is generally rectangular in shape. The walls are constructed of a mixture of light- and dark-colored bricks, and large arched windows can be seen. An arched doorway is visible near the corner of the building at center. Several chimneys protrude above the level of the terracotta tile-covered roof. At right, several automobiles are parked in front of the building, and people can be seen standing nearby. A paved street runs across the image in the foreground.
