Saw this poster on BoingBoing:
Hugh Electronic sez, “The I.W.W. hired Eric Drooker to design posters for a general strike which he is told, now appears imminent in Wisconsin. The Industrial Workers of the World asked him to design versions in Spanish and Arabic, for international solidarity.”
I doubt that general strike is actually imminent in Wisconsin, but one has to admire that poster. Of course, we love black cats, and black and red is great color combination.
