That’s the one I got!!
I got a reply! Yay! I wrote a letter to Pixar asking for Pete Doctor’s autograph January 24th, got a reply February 24th, and recieved it today. I’m so happy! And the signature looks real! I also sent a letter asking for Andrew Stanton’s autograph December 16th along with a picture I drew of WALL-E that I said I wanted him to keep. Still no reply from that one yet.
After almost exactly 8 months, I got a reply! I’m so happy! 
The letter was in the same format of all the other ones posted here (“Sorry for the late response, working on TS3, etc.”). I’m so glad I got a response, though, I wasn’t expecting anything at all.
Haha I’m also from sweden! I would love to get an autograph from Lee Unkrich or John Lasseter… It will probably take a few months xD But I will definitley try!
Yay, congratulations, IncredigirlVirginia, skunklover and Bryko! So glad that you all heard back from Pixar.
No. Way.
I just sent my letter I’m hoping to get an autograph from Lee Unkrich. Wonder how long it will take? A few months maybe 
I just wanted to share with everyone a few of the amazing successes I have had with Pixar. I have a few successes from different animators and people at Pixar but I want to share my favorites, and they are the one’s I have gotten from Pete Docter. These are amazing, and Pete is such a nice guy, and I can’t thank him enough.
This is a poster Pete sent me along with a letter with a sketch of Kevin on it!
Here is a drawing of all the characters of UP on a sheet of Pixar stationary.
A letter that Pete wrote me with some sketches on it.
Here are a few sketches Pete did on some artist sketch cards I sent him:
That’s an amazing collection of sketches from Pete Docter, [/b]wfdowns3[/b]! I love his version of Kevin. Thanks for sharing those with us!
I love how Pete always puts in those doodles. It certainly seems like he really appreciates people writing to him 
Wow! Very incredible reply there. I only got to talk to him very briefly, but he really seems like a great guy. Congrats!
I got my autograph from Elissa Knight (EVE) in the mail today, right in time for my birthday tomorrow!
I’ll be sure to upload a picture soon, it’s a really neat glossy picture of EVE
Here is what I recieved from Elissa Knight, I sent a letter to her in Jan and got it the day before my birthday! (April 15, which coincidentally happens to be her birthday as well). I’m still wating for a reply from Peter Sohn.
Sorry that it’s not the greatest of qualities!
That’s so cool, ellie-jessie-eve! And what a coincidence that you share the same birthdays, and that the autograph she sent you arrived a day before your birthday. Quite the early birthday present! She’s got a nice signature as well, I like the way she’s done her ‘E’ in ‘Elissa’. Thanks for showing it to us.
ellie-jessie-eve - What a lovely birthday present! That was very nice of her to reply to you, and, yes, what a coincidence it is that her birthday is on the same day as yours! Thank you for sharing this with us.

Wowzah! Such great stories on here. Congrats ellie-jessie-eve, that’s gonna be a hard b-day gift to top from now on
I’ve had these since the middle of February after I sent it in the middle of November. I was so excited that day! 
EDIT: Sorry, I was slightly concussed when I typed that. I was actually November, not December. Again, I apologize.
pixarfan9099, how cool! Congrats! And such a fast response.
Wow, pixarfan9099! I’d do anything to get an autograph from John Lasseter. He’s a legend and my hero. The best guy who ever lived. Congrats!
Cool stuff, pixarfan9099! I agree with gazelle, that was one fast response. Thanks for showing that to us!
