I sent a letter, SASE and photo. Today I received my photo back signed and personalized.
Address used:

Congrats! I hope he signs the photo I sent to him last week; it was a picture from Dumb and Dumber though...and he seems like he's into serious acting these days so he may not sign it if he feels it is "below" him, which I would understand.
lol nice success. you told me you had the smaller photo of the same one i got back. looks great. he signs really quick what a nice guy jeff daniels is.
