I have a FDC signed by Gus Grissom. The issue is this was post marked AFTER the death of Gus Grisom. It came with a Steve Zarelli COA. Boy, was I taken to the cleaners. Steve Zarelli knows squat about autographs and even less about space history. Ever read his bloggs ? They are a joke ! He is a joke! I wish he would stopbeing an expert and get a real job someplace. He needs to find something that he is truly good at. His authentications are hurting this hobby. He is snowing a lot of people including himself. I am embarrassed for the guy. He writes bloggs using stuff he made up and people are gullable enough to believe it all.
