Thomas Nast cartoon, "The American River Ganges - The Priests and the children," 1871. Depicts Tammany and Boss Tweed as allied with the Catholic Church in an assault on the American public school. This has been called the most powerful anti-Catholic cartoon ever drawn in the U.S. Also anti-immigration, the cartoon shows Catholic cardinals as alligators attacking school children thrown to them by Tammany Hall politicians.
