Description: A few weeks after the 9/11, an FBI agent called the Whitney Museum of American Art and asked to see a drawing on exhibit there. The piece was by Mark Lombardi. Just months earlier, the artist was found dead in his studio. Although the official cause of death was documented as a suicide, there have been many doubts. Using just a pencil and a huge sheet of paper, Lombardi had created an intricate pattern of curves and arcs to illustrate the links between global finance and international terrorism.
