Shots fired in the Knicks/Nets rivalry

Somebody alert Marty Markowitz! Some enterprising trickster has struck a blow for Knickerbocker supremacy with the above “Knicklyn” sticker. Not only is this an attempt to put a Knick foothold back in Kings County, but they were even able to slap it in the Barclays Center subway stop. Who are you, mysterious sticker bandit, and where else have you tagged up in an attempt to take back the borough for basketball fans with taste?
