Over the last two years artist Erin Crowe has created nearly 50 paintings and sketches of Federal Reserve Chairman Alan Greenspan. Today, on his final day as Fed Chairman, in front of the cameras at CNBC world headquarters, Erin is painting her final Greenspan portrait. Included with the painting is a DVD chronicling Erin's on-air creation. Proceeds from the sale of Erin's final Greenspan painting will go to Autism Speaks. Autism Speaks launched in February 2005 to help find a cure for autism by raising the funds that will facilitate and quicken the pace of research, to raise public awareness of autism, and to give hope to all those who suffer from this disorder.
