When Gary George bought a truckload of video tapes for $ 218 from a US government surplus auction more than 40 years ago,
Fortunately, he decided to hold on to the three tapes labeled "Apollo 11 EVA", in 1969.
Now the tapes – which include Neil Armstrong's famous words "That's one small step for man, one giant leap for mankind – Sotheby's in New York, where they are expected to fetch as much as $ 2m.
The collection also includes footage of Buzz Aldrin walking in minimal lunar gravity, planting the US flag on the moon. It also shows the crew's call with Richard Nixon.
George, now 65, which is astonished. "The retired mechanical engineer from Las Vegas told Reuters. "I'm selling them to TV stations just to record over."
George thinks he's about to pay $ 50 each. Nasa labelled reels.
"He was really into the space program and said, 'I think I hang on to those. They might be worth someday. So, for that very reason, I pulled them out and hauled them around the country for the next 43 years. That's how they come alive. "
In 2006, NASA admitted that they could not find the original video recordings of the landing. It was not until two years later when George Was on Holiday with a friend who worked at Nasa.
"Quite frankly, I was sitting at the table drinking a beer and I said 'Well, damn, I've got them,' "said George.
He did not have the equipment to watch the tapes, but he just started talking about the footage for the first time in a special studio in California.
