Here’s a short-lived series that appeared in the top-of-the-line version of the McClure Sunday comics section (the one with Billy Bounce, Simon Simple, etc.).The Baby ran from December 25 1904 to March 5 1905. The feature was never signed, and I tend towards it being by a cartoonist not in the usual McClure creator corral, while Cole Johnson suggests it might be Mark Fenderson’s work. The ugly mug on that baby does put me in mind of Fenderson, so Cole may well be right (as usual).
Thanks to Cole for the scan!
