# Philadelphia's Air Raid System

Civil-defence diagram for Philadelphia: a bomb strikes a house, a warden reports to a control centre by telephone, and arrows send fire, police, medical, repair and other units back to the house. Circular insignia for each volunteer corps surround the sheet. It mainly informs; the fear-appeal is faint and rests on the bombed house.
