A Double Whodunnit

Fiona Bruce and Philip Mould investigate the origins of two paintings by unknown artists dating back to the 18th and 19th centuries, which unusually for the period, depict black subjects. One is a portrait of Dido Belle, a famous former slave adopted into an aristocratic English family in the 1760s, while the other depicts two children against a tropical landscape, and is believed to have been painted as a protest against the slave trade.
