This image of the exhibition
of Joice Heth comes from Barnum's 1855 autobiography The Life of
P.T. Barnum Written by Himself. In the book, it illustrates a passage
describing how a Boston woman closely examined Heth to determine if
she was a machine or a human. Heth, in the background, looks far less
grotesque than she did in the poster which Barnum used to advertise
her in 1835.
