The first comprehensive volume ever devoted to the 1861-67 series, is an important landmark in the literature of classic U.S. stamps. Although the book concentrates on the lowest denomination of the 1861 series, the 1-Cent stamp is found in combination with all other values and was used in every conceivable postal application. This opens the text to a discussion of the complete range of philatelic lore for mid-century America, and results in an encyclopedic introduction to virtually all aspects of the postal history of the 1860s.
