Man finds $100,000 Superman comic in house he bought for $10,000

A Minnesota contractor who plunked down $10,100 for a fixer-upper home found a 1938 Superman comic book in the walls that could be worth more than $100,000.

You can't blame David Gonzalez for feeling like a superhero these days.

The Hoffman, Minn., man, who does construction and home remodeling for a living, found a 1938 Superman comic book in the wall of a house he was gutting in Elbow Lake, Minn.

Gonzalez paid $10,100 for the house, a fixer-upper with a torn-up roof. The value of the 1938 Action Comics #1 book? About 10 times that much.

"I knew it was worth money,” Gonzalez, 34, told The Star-Tribune. “But I had no idea how much.”

The comic book was found amid old newspapers used to insulate a wall of the house, according to the Star-Tribune. It features the first appearance of Superman, who is seen on the cover lifting a car.

Gonzalez put the comic book up for auction at comicconnect.com, and by Wednesday it had attracted a high bid of more than $113,000. The auction ends June 11.

"The most important comic book in the history of comic books," the auction item description says. "This is the introduction of the archetype of all other heroes to come. Superman transcends comic books and pop culture. He is an icon of Truth, Justice and The American Way!"

The comic would have been worth even more had the back cover not been torn during an argument Gonzalez had with one of his in-laws. But Gonzalez isn't complaining.

“I am a humble working guy, so I didn’t get too excited when I found it with old newspapers stuffed in the walls,” Gonzalez, a father of four, told the Star-Tribune. “Money won’t buy you happiness.”

As for the house that Superman "built?" Gonzalez reportedly plans to finish the rehab, but swears he will never sell it.
