Philadelphia: Pennsylvania Committee for Total Disarmament, 1931. Four-panel leaflet, toned around edges, otherwise very good.
"The next war will be an airplane war. Against airplane warfare there is no defense... The next war will be waged from the air against helpless populations. The next war will destroy civilization." Argues that "Defense is impossible. Let us disarm and put our trust in justice and fair dealing, rather than in force." Advocates a Constitutional amendment banning war preparations.
