A couple of years ago I took my kids to a Chad Marshall autograph signing at the Alderwood Mall Pro Shop. The true reason I we went is because I played a lot of Destiny 1 and had found out that it was a video game that he played. So I got a screenshot of one of his in-game characters for him to sign. When it was our turn to approach I first had him take a photo with my kids and then I plopped the screenshot in front of him. He barely blinked and just began signing it.
