These are the Butler buildings that served as the Page schools from 1958-1959 or 60. The permanent school was under construction and completed about 1960. These three buildings were located on the curve of South Navajo Drive. You can get a better feel for where they were located by looking at the bottom center of the aerial picture I posted [here].
The permanent school buildings were completed in 1959-60 and are located on South Navajo Drive, across from the Date Street intersection. These were originally called the A, B, C (Gym), and D buildings.
