The Chicago International Poster Biennial is a not-for profit organisation established to promote visual literacy, multiculturalism, and international cooperation through the poster work of artists from around the world. The first Chicago International Poster Biennial was held in 2008 with a primary goal in mind: to help realise posters as the quintessential public art form, engaging citizens at street level.
This years exhibition has an amazing selection of posters. Running until 28 July, this is not one to miss.
