'Batman 1', which features the first-ever appearances of the legendary characters - Joker and Catwoman, will go under the hammer at Heritage Auctions' Comic and Comic Art auction in August.
At present, the aforementioned comic is the sixth most-valuable comic book of all time and includes cover art by iconic illustrators Bob Kane and Jerry Robinson, Huffington Post reported.
The book, which has a 9.2 grade cover, was previously auctioned two years ago for almost 450,000 dollars.
The auction will also contain Frank Miller's black-and-white cover art for 'The Dark Knight Returns 2,' combining the now iconic storyline with Miller's signature grit.
The drastically gruesome depiction of Batman's face is set to sell for more than 500,000 dollars.
The auction will be held between August 1 and August 3 in Dallas, Texas.
