Fox's Gotham has an official site called Gotham Chronicle, which is designed to sort of resemble a real-life news outlet. The site posts photos from the TV series, and what's supposed to look like reports on the happenings with the Gotham City Police Department.
In the latest post (Nov. 20) we have a pic that seems to tease a future appearance by The Joker. On the other hand, could it just be a copycat of the late psycho Jerome?
Have a look at the pic below and decide for yourself.
