I would say Dirk Nowitzki of Dallas Mavericks. He was great to fans and he signed everything TTM. That was a nice gesture for an All Star and future Hall of Famer.

Also, the late Coach John Wooden of UCLA, he sent an additional signed picture of him and a signed business card of him. RIP Coach.

Very cool, thanks for sharing guys! Yesterday, for the first time, I got a book from someone when requesting an autograph. I was trying to get S. Truett Cathy (founder of Chick-Fil-A) to send an autographed pic, and while his sec said that he did not have any autographed pics, they sent me his book, "How Did You Do It, Truett?", which I thought was cool. Wish he would have signed it though! :/

James Earl Jones signs anything for everyone.

One of my best successes was voice actor Eric Loomis, who played Iron Man in Avengers: Earth's Mightiest Heroes. Not only did he sign my 2 trading cards, he also sent a 2-page handwritten letter. Josh Keaton, from Green Lantern: the Animated Series, also wrote me a 1-page letter. A lot of these voice actors are super guys.

Sebastian Stan wrote a letter back on my 8 x 10.

KISS guitarist Tommy Thayer and drummer Eric Singer!

Wow, that's awesome!!! What a cool response! Thanks for sharing!

Author Chuck Palahniuk (Fight Club) not only replied to my letter with a two page reply but also sent me a box full of dollar store fun and two signed CDs.

I am curious to know who you guys have found to be the "best" autographers. Best may mean they are the most likely to respond, or respond quickly, or perhaps even write a note on the photo they send. Whatever "best" means to you, who do you consider to be the best, and why?

Look forward to reading what everyone thinks!
