Gary George was a college student when he bought reels of videotape from the United States space agency NASA at a government surplus auction in 1976. He spent $218 for more than 1,100 reels of tape. It seems that George made a good investment. He might become a millionaire this month when the company Sotheby’s auctions what it says is the only surviving original recording of man’s first steps on the moon. George is a 65-year-old retired mechanical engineer from Las Vegas. He spoke about the tapes in a phone interview with the Reuters news agency. George said, “I had no idea there was anything of value on them.” He added, “I was selling them to TV stations just to record over.” But three of the tapes are valuable. They record the July 20, 1969 moon landing of the Apollo 11 mission.
