Go here, this page lists the Artists in Alphabetical order. The artists who are underlined are the artists who have their own websites. Click on the artist's (if they are underlined)  website and find their e-mail address and send them an e-mail about autographing their Ponies for you. For the artists who do not have websites try Googling them to find any contact information. Or you can buy a Painted Pony that is already autographed right here.
