DC Comics - Property of Joker Designer Flask

The designer steel flask «Property of Joker» from DC Comics. The Joker possesses no superhuman abilities, instead using his expertise in chemical engineering to develop poisonous or lethal concoctions, and thematic weaponry, including razor-tipped playing cards, deadly joy buzzers, and acid-spraying lapel flowers. The Joker sometimes works with other Gotham City supervillains such as the Penguin and Two-Face, and groups like the Injustice Gang and Injustice League, but these relationships often collapse due to the Joker's desire for unbridled chaos.

Stand back, fool, he-he-he, I've got a bomb! Oh, right.
