Back in 1969 insurance companies weren't very optimistic about the odds of an astronaut making it back to earth after being launched in a rocket to the moon. The cost of life insurance for the Apollo 11 crew was astronomically high so they came up with a clever solution. A month before launch, the astronauts signed hundreds of autographs that were to be sold if they didn't make it back. From the article: "About a month before Apollo 11 was set to launch, the three astronauts entered quarantine. And, during free moments in the following weeks, each of the astronauts signed hundreds of covers. They gave them to a friend. And on important days — the day of the launch, the day the astronauts landed on the moon — their friend got them to the post office and got them postmarked, and then distributed them to the astronauts' families. It was life insurance in the form of autographs."
