Little Chauncey was a talking baby, but as you can see from the samples, cartoonist Chase Craig didn’t really capitalize on the idea. The baby just mouths punchlines appropriate for essentially any age. This series appeared sporadically in the Christian Science Monitor from October 18 1938 to May 16 1942.
Craig’s CSM features could disappear for months on end, so presumably he was submitting them in between other jobs. His submissions slacked off to pretty much nil after the end of Little Chauncey, apparently finding himself all booked up as a scriptwriter at Western Publishing.
