                                            Create a realistic portrait of John Rankin, an American abolitionist and politician, in a 19th-century style painting. Depict him standing in front of a backdrop of the Ohio River and the town of Ripley, Ohio, with a determined expression on his face. He should be dressed in formal attire, wearing a suit and a top hat, holding a book, possibly a copy of his notable work "Letters on American Slavery". Incorporate subtle hints of his involvement in the Underground Railroad, such as a faint image of a lantern or a network of tracks in the background. The overall mood should convey his strong convictions and dedication to the abolitionist cause.
