This is a Civil War Era Slave Sale Re-enactment in St. Louis.
A mock flyer is posted advertising the re-enactment of a mid-19th century slave auction January 15, 2011 in downtown St. Louis, Missouri. Some 150 re-enactors participated in the mock-auction on the steps of the city's Old Courthouse, as the first commemorative event in Missouri marking the 150th anniversary of the Civil War. With other sesquicentennial events in the South emphasizing "states rights" as the cause of the conflict, organizers in St. Louis said they wanted to stress slavery as the central issue of the war. Before the war, St. Louis, with its location on the Mississippi River, had been a primary hub for the sale and movement of slaves. The U.S. Civil War, which lasted from 1861-1865, resulted in the death of more than 600,000 Americans, more than in all of the country's other wars combined.
