UPDATE: Another Batman logo, this one sent to us by @KmWieckowski on Twitter from the Technology Drive location in front of Carnegie Melon

Our Friend @IntenseCaboose On twitter found one of the Batman Dark Knight Rises logos by the Science Center

The spray painted logo above has been put up in random places all over the world including spots in Pittsburgh. Warner Bros/The Dark Knight Rises launched a huge twitter campaign. If you see one of these logos in downtown Pittsburgh take a pic and tweet it with the hashtag #TDKR07202012 Each location that you tweet will reveal a single frame of the new trailer.
Here's the new trailer, couple shots of the Pittsburgh scenes mixed in there. It's amazing.
Here is a list of locations
