In 2007 Great Britain issued a set of six
stamps commemorating the abolition of the slave trade. The design on
the 1st value features a portrait of Olaudah Equiano, a Nigerian who
was born in 1745 and enslaved in 1756. He purchased his freedom in
1766 and wrote his autobiography, The Interesting Narrative of the
Life of Olaudah Equiano, in 1789. The book brought the horrors of
slavery to the attention of the British public and ultimately
contributed to its abolition.
The portrait of Equiano on the stamp is the
Frontispiece of his book. In 1792 he married an Englishwoman with whom
he had two children. He died in 1797. The slave trade was abolished on
English ships in 1807.
The map is of the Atlantic Ocean with the African
continent, Equiano's birthplace, North America, and Britain. The map
is not identified, but Acadia is identified as Nova Francia, so it may
perhaps be dated before 1764 when France ceded almost all of its
possessions in the Western Hemisphere.
