I wrote to Josh Gad on December 13th, 2016 and received this back in the mail today, May 15th, 2017! (You can see two more pictures on SurfmyPictures that I uploaded if you scroll down and click on a different one beneath it.)

The letter is definitely secretarial, but I think the autographs are real. It matches his autographs today, and they aren't exactly the same, meaning they aren't from an autopen or stamp. A secretary knows how to do the signature, but scarcely the "font" of the person's handwriting, and he wrote short messages on them, "warm hugs" the same way he did with another autograph. I'm leaning toward the possibility it's real! Opinions are welcome!
The address I used is a via venue address I found on Imdb. I believe the filming is over.
Thanks, Mr. Josh Gad!

I love hearing others' opinions! However, before you start commenting, please read this carefully:
I welcome opinions but will not obey orders and suggestions. So, please don't say, "Toss that in the trash," or, "Frame the autograph right away," etc. I understand that you're sharing what you'd do, but you can't make me do what you order--what I received in the mail is mine, not yours.
