More interesting background and visual source material for Satrapi:
A collection of Posters from the Islamic Revolution including this "Black Friday" poster, this Warholization of the Shah, a Revolutionary stamp, and this co-opting of the Solidarity logo. My favorite is the final selection, a child's painting of women and children visiting a cemetery. The detailed colorful garden-like environment (the visitors look like butterflies) brings us back to the the world of Persian miniatures.
Here is some photo documentation (Warning! Graphic!) of the Islamic Revolution and Iran-Iraq War (slideshows at bottom of the page).
