Superman / Batman #60

Francis Manapul's cover for this 2009 issue places Superman and Batman back-to-back against a moody cityscape — searchlights sweeping the Metropolis skyline as the Daily Planet globe glows in the distance — capturing the quiet tension that defines their partnership. The two figures loom large and contemplative, each gazing in opposite directions, suggesting the World's Finest are facing challenges that may pull them apart even as they stand together. "Mash-Up, Part 1" kicks off what promises to be a compelling new arc from writers Michael Green and Michael Johnson.
