Everyone is invited to celebrate the legacy of civil rights hero Martin Luther King Jr., by exploring black history and contemporary black life Wednesday at Clark College. A traveling exhibit of historical figures and an iconic, ground-breaking rapper from New York City will both be on hand during the day. The Black History 101 Mobile Museum, a collection of more than 7,000 artifacts that span all of black history in America — from the trans-Atlantic slave trade to the latest hip hop memorabilia — will bring a traveling exhibit to Clark called “Black Historical Figures from 1800 to Current Day.” It features iconic African-Americans in every area of life, from science to sports and politics to entertainment.
