Photograph of an exterior view of the Precision(?) Radiation Instruments building, [s.d.]. The one-story building with a flat roof can be seen at center. The entrance can be seen at center, while four square-shaped windows can be seen on both sides of the entrance. Plants and what appear to be small pine trees grow in planters underneath the windows. A larger tree can be seen to the left of the entrance. A sidewalk runs in front of the building and continues into the background at left. A street lamp with a sign reading, "Jefferson(?) Blvd." can be seen at left. A paved road is visible in the foreground. A sign reading, "[...]cision Radiation Instruments" is visible over the entrance. The "Pre" is not seen but is an educated guess.
