This engraving shows bodies packed into the cargo hold of a slave ship. First published in 1788 by the Plymouth Committee of the Society for Effecting the Abolition of the Slave Trade, it gestures toward the brutality of the Middle Passage from Africa to New World slave markets. By the end of the eighteenth century, the image had proliferated in British and American abolitionist propaganda in varied forms and with different accompanying texts. It remains today one of the most recognizable symbols of abolition and the transatlantic slave trade. The engraved illustration has caption: "Plan of an African ship’s lower deck, with Negroes, in the proportion of not quite one to a ton". Signed at end: By the Plymouth Committee, W. Elford, chairman. Printed as a broadside in Philadelphia, 1789 under title: Remarks on the slave trade.
