Items appear in great condition, but put please study photos since they are part of the description. There may be age related yellowing on the envelopes. They are new but have been put away for a long time. So new or used is subjective, you decide.  

This is from a large collection I inherited of Authentic NASA Commemorative items from a relative who worked security at Kennedy Space Center. He received these pieces as gifts of appreciation from NASA and various space program contractors.
