According to the owner he obtained these signatures on two separate occasions. He acquired the Bowie signature the day after Bowie performed at the Santa Monica Auditorium with Iggy Pop, at the Dallas Airport where they found him eating in a cafeteria, prior to his flight. The Mick Ronson signature was obtained at a later date, at a Licorice Pizza Record Store when the Ian Hunter/Mick Ronson band was doing an in-store signing.
