This is a bit off the Twain / Nast topic, but Nast did make some successful tours. His first began in October 1873 and he ended up making a $40,000 profit on it, making him a wealthy man. That $40,000 from 1873 would be worth $616,350 in today's currency. Nast's tours are discussed in Paine's biography of Nast, in chapters 31-32 and 58. In these tours, Nast drew cartoons while he was talking. That technique, which became known as giving "chalk talks," was later picked up by other cartoonists and by the early 1900s many popular newspaper cartoonists had lucrative side businesses making chalk talk tours. In a 1922 book on Chalk Talk and Crayon Presentation, Charles L. Bartholomew, who many probably know as "Bart" of the Minneapolis Journal, wrote that "Achievement in chalk talk began in America with Thomas Nast, in the United States, and J. W. Bengough in Canada. The chalk talks given by them were the big picture shows [movies] of their day and they played to packed houses." In his own book about chalk talks, Bengough cites Nast's success as the inspiration for his first tours. Nast was not only successful with his lectures but pioneered a new form of illustrated entertainment that was very popular through at least the late 1920s and is still practiced today. Bart was one of the most popular and influential cartoonists of the 1890s and early 1900s. He drew "Can the Missionary Reach This Old Savage?" the March 1901 cartoon of Mark Twain as a grass-skirted savage confronted by a missionary demanding a retraction of his comments about missionaries in China in "To the Person Sitting in Darkness."
