This online reproduction of an exhibit that debuted at Stanford University’s Cantor Center for the Arts in 2005 features more than 120 posters that depict, illustrate and analyze political collectives. Five months in development, it was part of a larger (and longer) effort, the epicenter of which, was a Stanford Humanities Laboratory project called Crowds. While most online exhibits are collections of multiple forms of media, this one presents a single graphic vernacular -- poster art between 1914 and 1989.

• A single window, the posters page, is the lion’s share of the presentation. Giving visitors an overall sense of the exhibit’s organization and scope, it does a really nice job depicting the scale of each piece relative to others in the collection.

• Supplementing the imagery are written descriptions of the intent of each poster and the political happenings of each period. We can’t praise these enough. Never pedantic, they are condensed, interesting, insightful and highly-readable.

• The site’s currently being used -- along with Crowds -- as course material for architecture, history and art history students.
