This would be a good place to have one or two illustrative primary documents inserted.

One of the most well known is:

Description of a Slave Ship. London: Printed by James Phillips [for the London Committee of the Society for Effecting the Abolition of the Slave Trade], 1789. Two broadsides.

A digitized copy of the original can be found here: https://dpul.princeton.edu/wa/catalog/qj72p788s
