Action Comics No. 1 is hailed as the most important comic ever published, the auction house said.

Heritage Auction said that Superman remains "remarkably like" the current-day superhero.

In the comic book, Heritage Auction said that Superman faced off against "unjust imprisonment, spousal abuse, disarmament and drunken driving," according to author Les Daniels in Superman: The Complete History.
