Angelic sigil in 30 Rock?

[caleb]

First off, this is a bit off topic. I thought that this forum was the best fit, but admins feel free to move it. So as I was watching 30 Rock (one of the best shows ever!), season 3 ep. 12, It happens that a character gets tagged with spraypaint while in the ghetto. I was very shocked when I saw that what had been painted on his back looked like an angelic sigil. I don't have enough experience in that particular flavor of magick to identify it on sight and my researches haven't yielded anything, so I'm turning it over to this forum, hopefully someone can tell me whose seal this is (it's starting to bug me lol).
