On 18 October 1896, what possible first was "The Yellow Kid"?

The Yellow Kid was a bald, snaggle-toothed, barefoot boy who wore an oversized yellow nightshirt and hung around in a slum alley typical of certain areas of squalor that existed in late 19th-century New York City. Hogan's Alley was filled with equally odd characters, mostly other children. With a goofy grin, the Kid habitually spoke in a ragged, peculiar slang, which was printed on his shirt, a device meant to lampoon advertising billboards.
