The National Library of Medicine has the world's largest collection of poster art dealing with questions of health in the United States, so it would stand to reason that it would be able to sponsor a fine online collection of the various ways in which visual culture has been used to inform the general public about a number of health concerns ranging from lead poisoning to tuberculosis. Visitors to the site will want to begin by reading the introduction to the exhibit which offers a brief explication of what precisely constitutes visual culture, along with providing a few preliminary examples of early attempts to educate the public about different public health issues through broadsheets, leaflets, and posters before the 20th century. After that, visitors will want to peruse each section individually, as they all contain a selection of posters that have been thematically designed to convey important messages about each different public health issue in a way that commands the attention of the viewer and is provocative.
