On July 20, 1969 -- Apollo 11 landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the moon. In celebration of its 48th anniversary, Sotheby’s New York, one of the world's oldest auction houses will be offering the bag that was used by Neil Armstrong on Apollo 11 to bring back the very first sample of lunar material ever collected to Earth.

Traces of the moon dust and small rocks are still deeply embedded in the fabric of the bag, which is labeled “Lunar Sample Return” in bold black letters, giving a collector the chance not only to own some of the first lunar material ever collected, but also an exceptionally rare relic of one of humanity’s greatest achievements -- landing on the moon.

Cassandra Hatton, Vice President and Senior Specialist in charge of the sale commented: “This seemingly modest bag was part of mankind’s greatest journey, and played a crucial role in the single most important scientific task of the Apollo 11 mission – to bring back the very first sample of lunar material ever collected. To be able to see such an object in person is a once in a lifetime opportunity. It is one thing to read about going to the moon; it is quite another to hold in one’s hands an object that was actually there, and that still carries traces of that faraway place.”

Nearly all of the equipment from that historic mission is housed in the U.S. National Collections at the Smithsonian, however, a recent court ruling has allowed this to be the only such artifact to be sold to the public.

You'll have a chance of owning the bag which will be offered in Sotheby’s inaugural Space Exploration sale on July 20, 2017 (National Moon Day) -- and it's suggested to be sold for around $2 to $4 million USD.
