Barry Alpert / Silver Spring MD US / 11-2-11 (4:22 PM) Pleased to have a chance to warm-up before the internationally-known visual artist Julie Mehretu lectures on her work at the Smithsonian American Art Museum (aka SAAM) in a few hours. Perhaps a series of additional texts will follow; I've been intrigued by this artist for some time.
