Charles 'C' Frank King (1839 - March 17, 1887) was a lithographer, publisher, and print salesman active in Boston during the late 19th century. Per some sources, King was not a lithographer, but contracted with other companies, such as the firm operated by Charles Crosby. Other sources, including his obituary and U.S. Census records, identify him as a lithographer. Born in England, King arrived in the United States shortly before the American Civil War. He enlisted in the Union Army on July 15, 1862 in New York City and served with the 145th New York Regiment. He eventually became a lieutenant in one of the regiment's companies. He mustered out on April 7, 1863. After the war, King was active in Grand Army of the Republic (G.A.R.) circles, and even attended several of their annual encampments, including the 1886 event in San Francisco. He married Clara M. Cole on January 1, 1872.
