My first African-American stamp was Paul Lawrence Dunbar, a black inventor. There have been dozens of black American heroes printed ever since. We are even blessed with an African-American President, Barack H. Obama, who will also have his own US stamp one day.
Some collectors of African-America heritage use the dozens of Black American Hero stamps to teach their children the powerful roots of their heritage. This is another excellent example of stamp collecting instructing children on powerful life lessons.
