Digital Archives of Caribbean and Latin American Ephemera - Princeton University"The bulk of the materials currently found in the Digital Archive were originally created around the turn of the 20th century and after, with some originating as recently as within the last year. The formats or genre most commonly included are pamphlets, flyers, leaflets, brochures, posters, stickers, and postcards. These items were originally created by a wide array of social activists, non-governmental organizations, government agencies, political parties, public policy think tanks, and other types of organizations in order to publicize their views, positions, agendas, policies, events, and activities. The vast majority are rare, hard-to-find primary sources unavailable elsewhere."
