'Dark Knight Returns' No. 2 Cover Fetches $478,000 at Auction
PHILADELPHIA (AP) -- Heritage Auctions says the original pen and ink cover of The Dark Knight Returns No. 2 drawn by artist and writer Frank Miller has sold for $478,000 at auction.
A near-mint copy of "Batman" No. 1 has also sold for $567,625 at the auction. The auction house said Friday that the buyers did not want their names disclosed.
Miller's cover is the first to be sold from DC Comics' 1986 four-issue "Dark Knight" miniseries.
The copy of "Batman" No. 1 from 1940 shows Batman and Robin swinging in front of a Gotham City skyline. It was auctioned on behalf of Tadano America Corp.
The record price for a comic book remains with "Action Comics" No. 1, selling for $2.16 million in 2011. It featured Superman's first appearance.
