Things You'll Need
Instructions
Determine what materials you would like to mail off to get autographed. Magazine covers or photo pages within magazines are attractive pieces for signatures. If you have a photo of a star you can send this, as well. Photos or magazine covers will require 9 X 12 envelopes with a piece of cardboard to prevent bending, as well as more postage. Check current U.S. Postal Service rates. If you want to get a signature on an index card or other small, flat object, you can just send a standard envelope with first-class postage.
Find an address for the celebrity to whom you wish to send the autograph request. There are a number of websites online that list addresses for celebrities of all fields, from movies to television to politics and science. The best of these is stararchive.com, which lists addresses and autograph request success rates but costs a few dollars a month.
Write a letter to the star. You should know their career accomplishments and note some of them in your letter. You should explain why you are a fan and how much it would mean for you to receive their signature on your item. Don't just send requests to random celebrities. Send them to stars you actually admire so that your true fandom will come out in the letter. The assistant who reads the letters may pick up on your lack of sincerity and toss your request in the trash.
Prepare a self-addressed stamped envelope. Celebrities aren't going to add postage or prepare an envelope to send your item back to you, so you must include a SASE along with your letter and item in the envelope you mail to them.
After preparing the envelope, mail it and don't get discouraged. You will get some requests back in a week or two, but some could take much longer. It's not unheard of for autograph seekers to get their memorabilia returned to them signed years later.
