Before there was home mail delivery, slaves often carried letters to and from U.S. post offices or directly to recipients themselves.
Now the Smithsonian’s National Postal Museum is recalling that piece of postal history in a new exhibit opening Thursday. "Freedom Just Around the Corner: Black America from Civil War to Civil Rights" is the museum’s first exhibit devoted entirely to African-American history.
