A collector has sold a Batman No. 1 comic to an investment partnership for $850,000.
Dallas-based Heritage Auctions arranged the private transaction and announced the sale Thursday.
Heritage vice president Ed Jaster says the collector had paid $315,000 for the comic about two years ago. The comic book cost 10 cents when it was published in 1940.
Jaster says the comic is in near-mint condition. The identities of the seller and investors were not revealed.
Jaster says Batman first appeared in Detective Comics No. 27 in 1939 and became so popular that he got his own series the next year.
