I recently learned about Signs of Conflict, an on-line archive of political posters from Lebanon’s Civil War covering the years 1975-1990. It’s a very well organized collection. They have two different on-line exhibits that display their collection in two different ways. The first is organized chronologically, identifying each poster by political faction and year. The second focuses on the themes, icons, and symbols found in the posters. Personally, I’ve enjoyed just browsing through the exhibits, but an image database like this could also make for a great teaching tool.
