A comic book has sold for a super-sized, record-setting price. It is one of the few copies of the comic book that introduced Superman to the world. The comic, published in 1938, sold for $3.25 million in a private sale.

ComicConnect.com is the online auction and consignment company that announced the sale. The hefty price tag beat the previous record for the comic. In 2014, another copy of the same comic sold for slightly over $3.2 million.

The famous comic “really is the beginning of the superhero genre,” says CommicConnect.com’s Vincent Zurzolo. The book introduced readers to Superman, disguised by the name Clark Kent. The comic explained how the superhero came to Earth from another planet. He could lift a car with superhuman strength, outrun an express train, and “leap tall buildings in a single bound.” (Superman didn’t fly in this comic. Writers later gave him that ability in the 1940s.)

Originally, hundreds of thousands of copies of the comic book were published. Copies sold for ten cents each. Collectors estimate that only about 100 of the very first Superman comics exist today. Of those 100, not all are in good condition.

Mr. Zurzolo says that the latest copy to sell is one of the best-kept ones. “There’s no comic book that you could value higher in terms of a comic book than Action Comics #1,” he says. Cable News Network reports that this particular copy was “buried in a stack of old 1930s movie magazines.” It had been sold at least three times before.

“This is an 83-year-old comic book in near-pristine condition––and it’s a sight to behold,” says Mr. Zurzolo. (Kind of like the comic’s own superhero!)
