Here's an illustration I did to accompany a commentary in today's Philadelphia Inquirer by John Haigis, who serves on the Darby Borough Historical Commission and is the webmaster of The Darby History website.
The article is about the lessons we can learn about slavery from an archeological dig going on at the President's House in Philadelphia. It discusses one of Washington's slaves, named Hercules, who was considered a well-off slave. He was allowed to sell leftover food, earning about $200 a year. With that money he bought clothing, a watch, buckles for his shoes and even a cane.
