Walk into the National Portrait Gallery in Washington, D.C. right now and you will find a painting that has been ripped to shreds.

They are works by the artist Titus Kaphar. He takes familiar images and remakes them. Maybe he pulls a hidden figure to the front.
His work often confronts the history of slavery and racism in the United States.
