You best bet is to contact management companies. Companies that manage bands are usually good about donating signed band items. Sports organizations are usually good too. Most want you to fill out a form with your charity's info and info on the even that you're planning. Music and Sports will give you the greatest return because they normally send multiple items. Actors/actresses may only send a signed photo. You can look through the DB and see who's had success with them.

May want to contact movie sets, production companies and agents...

Hello everyone, the reason for this post is to ask for a little help. I am in the process of collecting some autographs for charity, and I was just wondering which celebrities are the best ones to get, also who will send them out for things like this. Should I send something of my own, or will they make a donation? I am new to all of this so please give me any information you can. Also how would I get autographs from the twilight cast, I see that being successful!
