Adam Hargreaves drew Mr Impossible for me

Charlotte got me a ticket for this event at Helm for my birthday. It was pretty cool. I love watching people draw, even if it's something super simple like a Mr Men character, apparently. He had a really nice-looking pen for lettering and I wanted to ask what it was, but also didn't want to be that "can I buy the same pen as you so I can also draw like you?" guy.
