Adventures of Superman » Adventures of Superman #40 - The Sound of One Clapping Hand, Part 1 of 2 released by DC Comics on January 2014.
Great all round, Superman and Joker taking the piss at each other by deconstructing each others characters. The deconstruction of Joker is just so provocative, exactly as you expect from Max Landis. The page with all the different Jokers was just awesome including the Heath Ledger and the New 52 faceless one.
The art was fantastic, with Joker swapping appearances from panel to panel and it really reflected his character, which is more than can be said for the writing. The characterisations were extremely off target, with the Joker sounding like a needy 'emo kid' and Superman coming off first as a hard-ass bully, then as if he's trying to get along with the Joker! The issue has no set up, no pay off but the 69p entry fee is justified by the gorgeous Joker panels...
