Justin celebrated a birthday while we were in San Diego for Comic-Con. He left our booth for a while that day and came back with two sketchbooks. He said he was going to celebrate hobbit-style and give presents. Worked for me.
Here's a sampling of my "behind the booth" doodles while the likes of Boba Fett, Batman, and various anime characters with unpronounceable names shuffled, slunk, and squealed past.
