"I had a huge amount to select from and narrow down," Ms Dottore said.
Posters are grouped by theme, with an explanatory text panel for each: war, feminism, race relations, workers' rights, sexual equality and environmental protection all feature.
Although the local politics of the time were dominated by the socially progressive Labor Dunstan government, some of the policies of the Fraser Federal government inspired strident responses from the poster makers, as did perennial issues such as uranium mining.
Hand Printed - Pre-Digital
While many of the posters are linked to specific events such as marches or rallies, others take a broader view. One series of images, dedicated to opposing apartheid, was produced in the Visual Arts Studio at Flinders by a South-African born PhD student.
While intended for cheap mass production, the works are all pre-digital.
"The artists were using the technology of the time, so they are all hand-printed," Ms Dottore said.
