This subseries contains an organization chart for Anti-Bombardment Control in the city of Honolulu as well as a map of the island of Oahu indicating anti-bombardment control districts. It also contains two maps of the city of Honolulu from January of 1938. In one, areas to be evacuated are shaded using colored pencil. In the other map, pencil markings identical to the first map are printed rather than hand drawn.
