Book excerpt: This volume is a collection of political cartoons by Thomas Nast that brought Boss Tweed to justice. The legendary Boss Tweed effectively controlled New York City from after the Civil War until his downfall in November 1871. A huge man, he and his Ring of Thieves appeared to be invincible as they stole an estimated $2 billion in today's dollars. In addition to the New York City and state governments, the Tweed Ring controlled the press except for Harper's Weekly. Short and slight Thomas Nast was the most dominant American political cartoonist of all time; using his pen as his sling in Harper's Weekly, he attacked Tweed almost single-handily, before The New-York Times joined the battle in 1870. The author focuses on the circumstances and events as Thomas Nast visualized them in his 160-plus cartoons, almost like a serialized but intermittent comic book covering 1866 through 1878.
