Here’s an advertisment for the movie The Town.  See how this already creepy poster gets even creepier when its half finished on the side of a huge building?!

I love catching these gigantic paint ads before they’re finished because it’s all the more awe inspiring to remember that someone…or something is actually putting in the man-hours to get this thing up.

Here’s another ad (same building) for Life As We Know It.  I wish I had taken pictures of the building each day that week because the amount of progress was incredible! 

After a little … research (google images) I tracked down these jawdropping examples of building art.  Enjoy:
