"Remember the Slave. Rebecca S. Hart"
Another version, this one hand-drawn, is inked on a quilt by Sarah Wistar in the collection of the International Quilt Study Center and Museum.
Wistar Family Tree Quilt, blocks inscribed 1842-1843

The Wistars were a prominent Quaker family in Philadelphia.
Rebecca S. Hart's block may have been
drawn from this image in the Liberator,
a leading abolitionist periodical.
Note that the figure is a woman. This kneeling slave headed the Ladies' Department in the paper during the 1830s.
