Career
Foster worked for John Inglis Company Limited producing Bren light machine guns on a production line on Strachan Avenue in Toronto, Ontario. She can be seen as the Canadian precursor to the American fictional propaganda tool Rosie the Riveter.
She became popular after a series of propaganda posters were produced.
Most images featured her working for the war effort, but others depicted more casual settings like Foster dancing the jitterbug or attending a dinner party.
