Have you seen this poster?
Apparently, it's beginning to appear in odd places in Los Angeles, but nobody seems to know who's responsible for it.
At this point, all I could find on the subject was an April 25 article from Bedlam Magazine:
A poster of Barack Obama in Heath Ledger-style Joker make-up with the legend 'Socialism' beneath it has been popping up recently on surfaces around L.A. It does not appear to be in the same category as the many benign take-offs on the Shepard Fairey 'Hope' poster, such as the one by Australian James Lillis (more of a straightforward spoof that merely substituted a Shepardized image of Heath Ledger as Joker on the Obama poster).
Here are Tammy's snaps:
Makes you wonder who's behind this.
*****Update: A version of this poster showed up in Atlanta (h/t NBer SUPERLEONE).
