A complete set of five profusely illustrated unused envelope covers which use the sport of boxing as a metaphor for the political and military conflict between the United States of America and the rebellious Confederate States of America in 1861. The images on each envelope depict the ultimately victorious President of the United States Abraham Lincoln and the President of the Confederate States of America Jefferson Davis in a boxing match. The envelopes were published by J. H. Tingley, 152 1/2 Fulton St. New York. Each envelope bears the statement "entered according to Act [of] Congress in the year 1861 by T. S. Peirce in the Clerks Office of the District Court of the Southern District of New York." Each envelope measures 6 inches by 3.5 inches (about 15.5 cm by 9 cm).
