The bulk of a man's childhood comic book collection that included many of the most prized issues ever published has sold for about $3.5 million.

Lon Allen, managing director of comics for Dallas-based Heritage Auctions, says Billy Wright's 1939 copy of Detective Comics No. 27 that features the debut of Batman got the top bid at the

New York City auction Wednesday. It sold for about $523,000, including a buyer's premium.
Action Comics No. 1, a 1938 issue featuring the first appearance of Superman, sold for about $299,000. And Batman No. 1 from 1940 sold for about $275,000.

Wright died in 1994. Relatives found the 345 well-preserved comics he bought as a child while cleaning out his wife's Virginia home following her death last February.
