The Oakland Museum of Contemporary Art (OCMA) hosts this extensive collection of thousands of digitized political posters. These posters are part of "All of Us Or None," an archiving project launched in 1977 by Michael Rossman. This collection includes posters related to organizations, labor issues, social movements, local issues, environmentalism, global issues, and much more. The posters are from around the globe and were created throughout the twentieth century. Visitors can conduct a keyword search to find posters of interest. Alternatively, the collection makes for interesting browsing: visitors can see thumbnail images of each poster as a grid or as a list. Unsurprisingly, this Oakland-based collection also includes a number of posters from the Civil Rights Movement and the Black Panther Party. The collection also includes a number of posters created by the La Raza Silkscreen Center and from Japantown Art and Media, both based in the Bay Area.
