My friend, Chicago artist Terry Dixon has an exhibit in Manassas VA:
"Telling that slavery did not end with the Civil War,Terry Dixon presents a body of work depicting African-Americans being forced to work for free from 1865 to 1945. His work is created through abstract digital images with acrylics, oil pastels and inks. Terry Dixon lives in Chicago where he continues his artistic discipline. He is as associate professor of computer arts."
The show runs from September 8th - October 26th. His work is remarkable, so go see it if you are in the area.
