[R. F. Outcault’s first Yellow Kid cartoon in the New York World, "Fourth Ward Brownies" referred to Palmer Cox’s merchandising skills. It appeared in Truth magazine on February 9, 1895, p. 10, and was then reprinted eight days later in the New York World. Cited by Richard D. Olson in The R. F. Outcault Reader vol. 9 no. 1 and R. F.
