This 1918 photograph captures a 'Children's Car' exhibit truck sponsored by the Council of National Defense, part of a nationwide World War I home-front campaign to reduce infant mortality during the government-designated 'Baby-Saving Year.' Displayed at a Cincinnati, Ohio exposition alongside Four Minute Men propaganda and child welfare posters, the vehicle illustrates how civilian volunteer organizations mobilized public health messaging as a form of wartime patriotism, blending maternal and child welfare advocacy with the broader war-support effort.
