Vintage pictures of the crew of Apollo 11 mission signed by its three Nasa astronauts,Buzz Aldrin, Michael Collins, and Neil Armstrong, the first manto walk on the Moon, are for sale. This is nowaday normal. But how much is it worth ? 3000 $ ? 7000 $ ?  

The reason commes from the nature of the space race. During the early years of the space program, NASA saw astronaut signatures less as a commercial opportunity and more as an outreach opportunity. Any body could ask t for an autograph with a self-addressed return envelope, free of charge. Astronauts, would respond , ensuring continued public enthusiasm for their program.
 

That program was designed to capture imaginations and it worked perfectly. but after a time, and as things became more popular, it became impossible to give everybody an autograph. NASA adopted the solution used by President John F. Kennedy: the autopen tool, a machine invented by Navy.
