Addresses:

For David Letterman's autograph:

Send an 9"x12" (Or 8"x10" picture envelope) Self Addressed Stamped Envelope (SASE) to the following address:

Dave Autograph Request
Susan Kanani
Late Show with David Letterman
1697 Broadway, 12th Floor
New York, NY 10019

Allow several weeks for a reply. Now I've heard you can send items to Dave to be signed, however I once sent my top ten book to be signed, and I never got it back, so be judicious.

For Paul Shaffer's autograph:

Send a 9"x12" (Or 8"x10" picture envelope) SASE to the following address:

Paul Autograph Request
Late Show with David Letterman
1697 Broadway, 11th Floor
New York, NY 10019

Allow several weeks for a reply. It took me about 3 months to get this autograph. He personalizes them, so be patient.

For Conan O'Brien or Max Weinberg's autograph:

Send a 9"x12" (Or 8"x10" picture envelope) SASE to the following address:

NBC
Late Night with Conan O'Brien
30 Rockefeller Plaza
Room 901W
New York, NY 10112

ATTN: PHOTO REQUESTS

Also you can head the address with "(Person's name) Autograph Request." Max's came in about a month or two and Conan's in about three months.

For Craig Kilborn's autograph:

I do not have up-to-date information since he moved to CBS. If anyone could provide me with an address, I'd appreciate it.
