Portraits of individual Africans who were enslaved and brought to the Americas are incredibly rare, and in virtually all instances the portraits were done long after the horrors of the Middle Passage. There is one clear exception to this rule, however.
On March 25, 2011 the UN called for an international day of remembrance of the victims of the transatlantic slave trade. Good. However, the resolution still does not hold anyone responsible, nor does it seek to offer redress.
