Space enthusiasts will soon have  chance to purchase  piece of space exploration history. Items from Neil Armstrong's personal collection of mementos are to be auctioned. Mr Armstrong was  first person to walk on  moon. A variety of artifacts from  July 20, 1969 lunar landing will go under  auctioneer's hammer. These include  US flag, a UN flag, state flags and commemorative medallions that were given to NASA astronauts.  auction house anticipates that the sale will be very popular. It said: "Space is one of  very, very few categories that every single person seems to be interested in....You show somebody something from  space program, and they are fascinated by it."
Neil Armstrong was born, lived and died in  state of Ohio. He kept his many space souvenirs in his house there. His son, Mark Armstrong, said his father never talked to him about what he wanted to be done with  huge amount of items he had kept. He said: "I don't think he spent much time thinking about it. He did save all  items, so he obviously felt they were worth saving." Mark and his brother Rick decided it would be best to auction  items to share their father's legacy. They had to restore many of  items. They also said it was becoming increasingly difficult to correctly identify some things as  number of living people connected to  Apollo 11 mission was decreasing.
