Olive Karlsen, Julia Canfield, Uncle Tom's Cabin, Karen's Office.

 This is an advertisement for Uncle Tom's Cabin. This is most likely an advertisement in the North, because the novel is scorned in the South. This advertisement shows how popular the book was, and how highly people thought of it. This shows how Uncle Tom's Cabin tore the nation apart, because it put the heavy unfairness of slavery in the spotlight.
