LB:EF - Easter egg?

I'm not sure if this is an easter egg or something that really exists in New York City. Check out this partial screenshot:

Notice the Superman symbol on the building? Weird.

UPDATE: Kevin Hoekman informs me that the building is exactly how it appears in New York City. I probably should've guessed that after reading about how they painstakingly reproduced the city for the game. Well, with that being the case, then my second guess is that it has something to do with "Seinfeld." I've heard that Jerry Seinfeld is a big Superman fan and always had some reference to Superman in every episode. Perhaps the symbol on the building had something to do with the show or is an example of life imitating art (though I am loathe to call that show "art").

UPDATE 2: Kevin says it's a comic book store. Thanks, Kevin.
