Communist Cartoons By New Yorker Artist

I originally saw a post about this topic on Boing Boing, but forgot about it until Retronaut posted about it as well.  Syd Hoff did hundreds of cartoons for The New Yorker, and also illustrated childrens' books.  In the mid-1930s, however, while his work was published in The New Yorker, he was also publishing as "A. Redfield" in The Daily Worker, a communist party newsletter.  Talk about playing both sides of the fence.  He did a series of cartoons called The Ruling Clawss with all of the wit of his New Yorker stuff, but coming from the other end of the political spectrum.
