Dude lives in a custom-built castle full of secret passages. He can afford the shipping.
Not to mention he payed his way onto the international space station and has essentially a museum in his home(they showed it off on some show or another). I am sure shipping to South Korea wouldn't be a issue.
I'm personally planning on nabbing ones for Ultima 4(which I finally beat two years ago and made a few screencaps), Ultima V which I am working on now, since I had to restart due to switching computers and took a while to find where I had my backup end game save for Ultima 4 uploaded too since I tend to find it's a bit easier starting with a Level 5 Avatar with all stats starting at 25, then it was rolling a new one since I often run into the occasional pack of Headless or Wisps that would wreck a rolled up Avatar and Ultima 6 once I finish that one again.
I plan on having them framed and put on the wall of my office. Still really cool that Richard is still willing to do this, he may seem a bit eccentric but he seems a genuinely cool guy.
