The auction was held at Bruun Rasmussen in Copenhagen, Denmark’s primary auction house. A copy of a school newspaper featuring the interview, as well as a collection of 23 photographs, were sold alongside the cassette tape. The tape sold for $58,300 to a buyer whose identity remains unknown. He placed his offer via telephone. “A recording like this is indeed very rare,” director Alexa Brunn Rasmussen told the BBC. “We are not sure that there are any other recordings like this one, because it’s an unofficial recording.”
