The record price for a comic book, already broken twice this year, has increased again.
A copy of the 1938 edition of Action Comics No. 1 sold Monday for $1.5 million on the auction Web site ComicConnect.com. The issue features Superman's debut and is widely considered the Holy Grail of comic books.
The same issue sold in February for $1 million. That number was quickly bested when a 1939 comic book featuring Batman's debut sold for $1 million and change.
The issue that sold Monday was bought from a private collector and then sold by Stephen Fishler and Vincent Zurzolo, the co-owners of ComicConnect.com.
Fishler declined to name the buyer but said he was "a hardcore comic book fan."
