Expositions, fairs, and festivals have been among the most ambitious clients in the history of commercial art. A single event might commission dozens of posters, each competing for attention in a city already full of them, which pushed designers toward bolder color, stronger composition, and more inventive typography than everyday advertising required. That pressure produced some of the most striking work of the 20th century. The period originals in this collection come from that tradition, across more than a century of public spectacle.
