What is a great African American cultural artifact?

For my Pan African American history class, we need to bring in an artifact. I have talked to a couple of African American friends, but they could not really think of anything. Now before I get comments about how this is not a place for homework, it is part of the assignment that we talk to others and I was wondering to see what you guys would think is a good artifact to either bring into class or a picture of the artifact. I need to be able to relate it to the African American culture from between 1865 and present. Anyone have any suggestions?
