WASHINGTON, D.C. - Pieces of African-American history made their way through Washington, D.C. on Sunday.
Tractor trailers carried a 1922 Pullman rail car and a prison tower from Angola, the Louisiana state penitentiary, to the National Mall.
The Southern Railway passenger car was modified with segregated seating, to comply with Jim Crow laws. Furthermore, the prison tower illustrates the incarceration of African-Americans in the 20th century and the link between the prison system and slavery.
They're being installed in the Smithsonian's National Museum of African American History and Culture, which is under construction.
