I've gotten fairly quick responses from Bea Arthur (sent a letter, pic, and SASE; received my photo back signed) and Jenna Fisher (sent a letter and SASE; received personalized and signed photo).

letterman i still waiting for 2 yrs now

skye sweetnam i beleve takes close to a year

try searching them in the database and see if there was success

Alright, well Lauren Conrad is one of the best signers in my opinion. She replied to me within a month.

Bob Saget:
Sent July 21st
Rec August 4th

Sent: LOR, Picture
Rec: My picture back signed and personalized (authentic), with another pre-print that was personalized to me.

Hope this helps,

Betty White is very good should see something soon. Have not triesd the others but i think Elton John would be a tough one to reply.
Good Luck!

Hi-
I am new here, but I have sent out 15 autograph requests in the last week. I was wondering what type of success you have all had with these celebs? (How fast they respond, if they do, If they personalize or if it is PP, etc.)

Here is the list of people I have written to:

Lauren Conrad
Spencer Pratt/Heidi Montag
David Letterman
Skye Sweetnam
Alexa Ray Joel
Betty White
Bea Arthur
Jenna Fischer
Sir Elton John
Bob Saget
Anthony Rapp
Adam Pascal
Fabulous Moolah/The Great Mae Young
Arn Anderson
Bruce Froemming

Any info would be helpful!

Thanks,
Brendan
