Hey guys, I'm looking for some people who have went through this process before. 20 years ago, my Grandparents sent me a '93 Cooperstown book and as a surprise they slipped in a 3x5 with Jimmie Foxx's autograph on it. I googled 'Houston autograph authentication' and there was only 1 place in Houston that seemed reputable. The only problem is, they never pick up their phone. I would prefer to keep it local but if I absolutely have to mail it out, I will.
