Real Banksy Or Faux Banksy?

I was riding my bike today, not too far from home, when I saw this graffiti painted on an abandoned building. I've ridden by this place dozens of times, and it wasn't there the last time I rode by it (sometime before Memorial Day).

It looks like it could be a Banksy. It's known he was in Chicago not too long ago-photos of a piece he did here are on his website.

Here's a closer view:



and a closeup of the figure:


That could be the artist's signature to the right of the figure, or it could be something someone else left. It doesn't look like Banksy's sig, but than again, it looks like most of Banksy's pieces are unsigned.

If you want to check it out for yourself, the building is located in Chicago at 9030 S. Hermitage (corner of Hermitage and 90th place). It's easy to get to if you're not familiar with the area, just get on the Rock Island Metra line. The building is about 1/2 block from the 91st St. station (the graffiti should be easily seen when riding the Metra northbound into downtown).

So, what do you think-real Banksy or faux Banksy? I'm leaning towards faux myself. although it would be cool if it were real.
