Who Is This Artist?

That is a real question.  Here is a selection of some art (second generation photocopies, courtesy of Ned Brooks), that was offered for sale nearly thirty years ago as by Donald Corley. Yet the art itself does not resemble any of Corley's that I have seen (in his books, in inscriptions, and in a portfolio issued in 1921), nor does the handwriting look like Corley's. (This art has a finer line, and a different kind of humor than Corley's art has.) Yet it does seem to date from the 1920s.  Does anyone recognize the art or artist?  (Click to enlarge.)
