Here’s more from this 1943 book I have.
Ralph Barton, Liberty 1929
J. Norman Lynd, Vignettes of Life 1930
Otto Soglow, Wasn’t the Depression Terrible? 1932
Alain Dunn, Collier’s 1937. I believe this is a different person than the “Alan Dunn” in The New Yorker. Those cartoons were all done in charcoal and wash.
C. W. Anderson, Ballyhoo 1937
Syd Hoff, Collier’s 1937
Ed Nofziger, Saturday Evening Post 1939
