No, sadly, it isn't real.
These sets are the work of Yaktuu of Flikr, and he has an entire zombie-themed set you can peruse.
Be sure to visit his page to see the full-sized versions of these pictures, so you can really appreciate the work put into them. He's even got a scene inside the bar:
Okay, that deserves some music:
Also available in Mario and Google versions:
Thanks for the post! (sorry for the late comment..)
Sadly it isn't real.. yet!
If you liked "the Win" in Lego it could one day become a real official Lego set - I'm not kidding.
It's actually fairly simple:
A few months ago Lego launched a website named CUUSOO, it's a platform where fans can post their creations. The community can then vote for the ideas they like best, if a project gets enough supporters Lego will consider making it a real set - how's that for a slice of fried gold?
I already have the support of Edgar and Simon (!!) but I need to let the community know about this... here is the link to the Winchester project on CUUSOO:

People need to register before they can cast their vote, it's free and it only takes 2 minutes.
There is a "tweet" and a "FB Like" option from the CUUSOO webpage - this is probably the best way to spread the word.
Cheers,
Yatkuu
Holy crap, they made it to 10,000! Now it's up to the lawyers to make things work, but this is super exciting!
And way to go, Yatkuu! It's cool to see good work get rewarded...
