A rare first-edition Superman comic book is expected to sell for more than £2 million at auction.
The Action Comic was the first to feature the superhero.
He is seen lifting a car over his head.
The comic was sold for £1.50 back in 1938 in a 200,000-print run.
It’s thought no more than 77 copies have survived.
Heritage Auctions will sell the edition.
A spokesman said:
“It’s the best copy of Action Comics No 1 we have ever offered and already the most valuable by far.
“It is the book in which Jerry Siegel and Joe Shuster introduced readers to Clark Kent and Lois Lane and ushered in the era of the Superhero.”
Heritage senior vice president Ed Jaster described the item as a “truly unique find”.
“This treasure has never left the family of its original purchaser.”
In the issue, Superman discovers his powers but uses them to “benefit mankind”, and rescues Lois from a gangster.
In 2018, DC Comics president Paul Levitz hailed the number one edition as “the singular most important comic book published in America”.
Another copy of Action Comics No. 1 was sold for a record £2.4 million in April this year.
