PHILADELPHIA -- It's the comic-book cover that captured the grim visage of an older, wiser and meaner Batman.
Now, the 1986 pen-and-ink creation -- drawn by writer/artist Frank Miller -- that is the cover to The Dark Knight Returns No. 2 will be sold next month in Dallas by Heritage Auctions.
It's the first cover from DC Comics' 1986 four-issue Dark Knight miniseries to be sold and is expected to go for more than $500,000.
Miller's story "radically altered the direction of comics," said Todd Hignite, Heritage's vice-president.
"For fans of modern comics, this drawing is where everything really begins," he said. "This moment defines Miller's Dark Knight, and the modern day perception of Batman, like no other drawing."
Also up for sale is a 9.2-graded copy of Batman No. 1 from 1940 that shows Batman and Robin swinging in front of a Gotham City skyline. A similar copy sold for $850,000 in 2012.
The record price for a comic book remains Action Comics No. 1, which sold for $2.16 million in 2011. That featured Superman's first appearance.
