What are some artifacts I can make for my project (politics)?

My subject is 1990s politics. The ignment requires an "artifact" for each subtopic- mine are Oklahoma City Bombing, the Million Man March, and Hong Kong Returns to China. So i was thinking of making a powerpoint and adding clips of the ceremony of hong kong returning to chinese rule. there is this good clip of them changing the flags. There is also a clip of Farrakhan's speech at the Million Man March. But I can't find an artifact for the Oklahoma City Bombing... can you think of other, creative artifacts i can create? i was also thinking of maybe making a fake brochure, like ones they would p out at the march... any other suggestions?
