"The Underground Railroad was a network of secret routes and safe houses used by 19th-century slaves of African descent in the United States to escape to free states and Canada with the aid of abolitionists and allies who were sympathetic to their cause. The term is also applied to the abolitionists, both black and white, free and enslaved, who aided the fugitives. Using vintage photography, slave journals and abolitionist letters, this flag book highlights the secret routes and "conductors" of the underground railroad." — Vamp & Tramp booksellers' website
