If Americans were asked to describe the Statue of Liberty without looking at it, most of us could probably describe her long robe, the crown on her head, a lighted torch in her right hand and a tablet cradled in her left. Some might remember it's inscribed with the date of the American Declaration of Independence, July 4, 1776.

But there's a significant detail most of us would miss. It's a feature that points to why Lady Liberty was created and gifted to us in the first place. At her feet, where her robe drapes the ground, lay a broken shackle and chains—a symbol of the abolishment of slavery.
