This sounds like some expensive insulation.
David Gonzalez recently discovered a valuable comic book hidden in the wall of his newly purchased home.
The comic, a 1938 Action Comics #1, featuring Superman, was sandwiched in among the newspapers that were being used as insulation.
Gonzalez's find is worth more than $100,000, but it could have been worth so much more.
