The Mad Men graffiti keeps on coming and the debate about 9/11 runs and runs.... what's your view? On the one hand we've got graffiti artists cleverly taking the image and adding whales, stunt bikers and Superman. Even the Occupy movement has got in on the act.
While on the other, we've an online spat amongst the blogging community as to whether the campaign is offensive and a desecration of the memory of 9/11 and the 'falling man' or jumpers from the Twin Towers.
Is the similarity intentional?  Anyone got any more examples to post? What would Banksy do with it I wonder? 

With added whale

Posters all over Manhattan

But when reflected in a phone box it does look very suggestive

Certainly getting a reaction
