Wired has a story on it.





The original owner of this computer bought the machine in 1981 at an Apple users group meeting in Santa Clara, California. By this time, the Apple I was at least 5 years old, and while it was by then obsolete, it still had a user base.
He arranged a visit to Apple Computer's headquarters in Cupertino, California, to discuss the possibility of adding disk drives to the computer. This Apple Computer visitor badge was left as a memento of his visit.
