The Joseph A. Labadie Collection (University of Michigan), contains posters which have been acquired over the past 100 years.
This database consists of images of those posters covering social protest movements such as Anarchism, Civil Liberties, Colonialism, Ecology, Labor, Pacifism and Sexual Freedom,
Some are from the first half of the 20th century, but the majority are from the 1960s and later.
