Jeesh, I knew that Chris. Why do you assume I didn't?
The Fat Kapitalist with Top Hat is Kitsch, was a standard caricature in cartoons by such as Robert Minor in The Masses. The CPUSA aligned New Masses continued that tradition later. (I have some back issues, one with an ad for the John Hammond organized concert @ at Canegie Hall, "From Spirituals to Swing, " that would have included Robert Johnson.)
