What does the robe of Muhammad Ali, one of Prince's guitars, Alex Haley's typewriter, and a key from a Birmingham jail cell that held Dr. Martin Luther King, Jr., have in common? They are all artifacts from the lives of African Americans who irrevocably changed our society. In Tavis Smiley's touring exhibit, America I Am: The African American Imprint, these objects and others related to innovative artists, activists and inventors make up more than 200 pieces that Smiley gathered from museums across the country.
