So, here's another effort by the Muni Adbusters, tweeted by a friend of a commenter (which is kind of better than a friend of a friend). This one would suggest that the culprit in this guerrilla art campaign/sly critique of capitalism is not the most careful of spellers — some have also pointed out the lack of familiarity with the real Tartine, which does not sell doughnuts. This time, it's jeweler and accused blood-diamond seller De Beers that they're targeting, except they spell it "Du Beers."

And yes, diamonds do equal blowjobs, so... not sure what the joke is there.
