According to Winter's journal his pencil sketch of Slocum in her cabin at Deaf Man's Village in 1839 is the only one of her executed from life. "The Captive Sister" portrait of Slocum, also known as the "Lost Sister of Wyoming", became his best-known work, especially after the news spread that she had been found and her story became famous. He charged $75 for the commissioned painting. The description of Slocum that Winter wrote in his journal closely fits his original sketch:Though bearing some resemblance to her family (white), yet her cheekbones seemed to have the Indian characteristics—face broad, nose bulby, mouth indicating some degree of severity, her eyes pleasant and kind.
