A US comic collector has been caught in Spider-Man's web, paying $1.1 million for a near-mint copy of Amazing Fantasy number 15 that features the wall-crawler's debut.
ComicConnect.com chief executive Stephen Fishler said that the Silver Age issue, first published in 1962, was sold by a private seller to a private buyer in Philadelphia.
It is not the highest price ever paid for a comic book.
That honour goes to Action Comics number one with Superman on the cover, which went for $1.5 million.
But Mr Fishler says the price paid is the most for a Silver Age era book.
The cover shows Spider-Man clutching a villain in one arm and swinging from his web with the other. It originally sold for 12 cents.
