Superman: The Man of Steel #12

From the streets of Metropolis to the rooftops above, something enormous and monstrous has literally burst through the city pavement — a massive, tooth-lined creature maw dominating the cover of this June 1992 issue, with cars and debris tumbling into its gaping jaws. Superman streaks downward through the urban canyon to meet the threat head-on, cape billowing as the tagline says it all: "Metropolis' Underworld Breaks Loose!" Cover art by Jon Bogdanove and Dennis Janke brings a wonderfully visceral sense of scale and urgency to "Panic in the Streets," a story crafted by Louise Simonson, Bogdanove, and Hilary Barta.
