When the title of the talk is broad, the danger is dullness. By figuring out the main concepts—freedom, justice, education—and creating icons to represent these ideals, I came up with a poster that tells you in a glance that this talk at Princeton is about issues that matter. Less is more in this poster. If I had used color images with lots of detail, the message would get lost. So I posterized the images into silhouettes and placed them in a V shape. I chose type reminiscent of Soviet-era posters. It took a while to simplify and posterize all the images, but I may end up using them again. Headshots of the speakers along with short bios let you know who will speak, and the day, date and time stand out.
