Heritage Auctions has sold the original pen and ink cover of The Dark Knight Returns No. 2 for a whopping $478,000 at auction.

The Dark Knight Returns written and illustrated by Frank Miller, was published in 1986 and it, along with “Watchmen,” by Alan Moore and Dave Gibbons, ushered in a new era of storytelling in comic books.

The Dark Knight Returns imagines the future of Gotham City, where crime and corruption are at an all-time high and Batman must come out of retirement to save his hometown. But this older Dark Knight has not mellowed with age. Along the way he picks up a new Robin, Carrie Kelley, who was the first female in the role. The Dark Knight Returns led to a creative revival for Batman that paved the way to the film franchise.
