Greetings,

I'm looking to find fairly priced posters with images (preferably images of the
protestors/victims) from as many of the following incidents as
possible for material for a Masters thesis:

* Tian An Men Massacre, Beijing, CN, 1989 (NOT the one with the 4 tanks)
* Kent State Incident, Ohio, US, May 4, 1970
* Bloody Sunday Massacre, Derry, IE, 1972 (this one if
possible-http://cain.ulst.ac.uk/images/posters/bsunday/poster28r.jpg)
* Taiwan 228 Massacre, Taiwan ROC, 1948(?)
* Jallianwala Bagh Massacre, Amritsar, India 1919


I don't want gory or gross pictures, just posters of the
marchers/protestors/victims.  Alternately, for the Taiwan and India massacres,
posters or large-scale photographs of the memorials that lay where they
occurred would be acceptable.
