Coburn and Archibald Henderson visited Mark Twain’s new home "Stormfield," in Redding, Connecticut, on December 21, 1908. Coburn, who had photographed Twain in New York in March 1905, made thirty to forty exposures, including autochromes. Henderson’s subsequent biography, Mark Twain, is illustrated with eight Coburn black-and-white images and two autochromes and retailed for five shillings. [1]
