They don't make comics like this anymore. Though published in 1990, this miniseries is a thoroughly committed throwback to the 1940s Golden Age. The story involves Batman and Superman switching cities as Lex Luthor expands his shady developments into Gotham and Joker creates mischief in the streets of Metropolis. The Joker here is unlike any you've seen, his conceptualization offbeat and old-fashioned he owns rundown apartment buildings rented out to hookers and junkies. Instead of threatening innocents, he engages in property warfare with fellow slumlord Luthor. It's different. Also Steve Rude draws one of the most distinctive Jokers around, very impish and with a slight potbelly.
