Stephen Stanton is the voice actor who played Captain Tarkin in season three of The Clone Wars. He is giving away free autographs (while his photos last). All you have to do is send him a SASE that holds an 8 X 10. I am sending mine to him today.
Also if you click like on his facebook page, he is ordering some kind of patch I think and will be giving it to the first thousand fans. The fan page is getting close to one thousand so you better hurry!
Here are the instructions to get an autograph...
