This Batman t-shirt features the Joker on the cover artwork for the influential graphic novel titled "Batman: The Killing Joke".

In The Killing Joke, the Joker escaped from Arkham Asylum and intended to drive Gotham City Police Commissioner James Gordon insane to prove that the most upstanding citizen is capable of going mad after having "one bad day". When Batman caught up to the Joker, he attempted to reach out to him to give up crime and put a stop to their years-long war. The Joker said it was far too late for that, and told Batman a joke that made both men laugh until Batman grabbed the Joker as the story ended, leaving it up to the reader to determine the Joker's fate.

The Killing Joke is widely considered the greatest Joker story ever told. Show that you are a fan with this The Killing Joke Cover Artwork Batman T-Shirt.

Fun fact: Tim Burton claimed that The Killing Joke was a major influence on his 1989 film adaptation of Batman.
