Hi guys could anybody please tell me how can I got autograph of Matthew gray gubler?

Hey.
I used that e-mail a while back and spoke to Matthew's friend. I asked for an autograph and received one - the picture is below. On the envelope there was a return address, here it is:

Matthew Gray Gubler
Criminal Minds
4585 Electronics Place
Los Angeles, CA 90039 USA

Hope it helps =)
Good luck!!

Maybe try emailing him @ letters@gublerland.com from what I hear he's usually pretty good at replying (when he can, I think his friend also helps him with emails sometimes) but its worth a shot. Good Luck and let me know how bạn go.
