Well, I didn't get many responses here but I tried my luck anyway.

Just in case somebody is looking for genuine Harrison Ford autographs, here is an example.
I’m surprised you didn’t get more responses from back in October. I see you’re a pretty new member here. I hope you won’t get discouraged. Sometimes it’s hit or miss. At times, things occasionally get overlooked. It happens to us all from time to time. But then other times, you will get many opinions. But you should stay engaged in this website. It’s the best site on the web for both diehard collectors and novices too. You can learn a lot and save yourself a lot of money too.
Thanks for the input. Our fellow member Mike Shepherd is very knowledgeable about Star Wars autographs. So Harrison Ford would be right up his alley. I’m not an expert on Ford’s autograph although I do have an abbreviated version on a Star Wars item I own. That’s a nice picture of Ford and a nice autograph too that is very likely real.
