Harriet Tubman was a heroic US Afro American woman who rescued many slaves during the slave era of the United States.
Her movement was metaphorically called the Underground Railway and many slaves rode on to their freedom.
According to Afro Americans of that era, Harriet Tubman comes around to rescue slaves in the thick of the night when normal people are alseep. She was that brave.
See photo of the extra realistic mural here.
One thing though: I would have preferred the mural to have a night time background not a day time background. Because most of her rescue operations were carried out at night.
Wow!
What a brave woman she was!
