Superman Comic Sells for $9 Million

Three brothers found a very old Superman comic book in their mother's attic. The comic was from 1939 and was the first Superman issue ever made. They decided to sell it at an auction.

The comic book was in very good condition. It had been kept safe in a box for many years. The auction house said it was one of the best copies they had ever seen.

The comic book sold for $9.12 million. This makes it the most expensive comic book ever sold. The brothers were very happy with the sale. They did not expect to find such a valuable item in their mother's old things.
