Artist Rick Celis clearly has a fondness for pop-culture send-ups, and for Gotham City. Although he was brought to my attention because of his mashups of Disney and Batman characters, it's his Joker parodies that really caught my eye.
Drawing inspiration from movie posters, album covers and beyond, Celis creates a series of fun illustrations with The Joker, Harley Quinn and their associates at their center. While the Peanuts and Breakfast Club gags are somewhat expected, the tributes to Marley & Me, the Beatles' Abbey Road and Gorillaz's Demon Days certainly aren't.
The latter two in particular stand out because he uses them to trace the live-action evolution of The Joker, from Cesar Romero to Jack Nicholson to Heath Ledger to Jared Leto.
