The Women's International League for Peace and Freedom issued | History

The Women's International League for Peace and Freedom issued this poster in 1924 as protest against the use of poison gas. Especially since the war had seen the increased involvement of civilians, it was worried it could be used on towns and cities. This fear would never go away as, for example, in 1939 and 1940 when gas masks were issued across Britain.
In any case, the 1925 Geneva Convention agreed to outlaw the use of poison gas in warfare.
