Alonso remarked on my Mark Kistler reference during the latest Ninja Mountain episode. I used to love watching Secret City on PBS, and was always trying to catch up with my older brother's skill whilst contributing to the family mural. I hadn't thought about it in years, but not too long ago we found his site and subscribed for my daughter. Here are sketches from a couple of episodes we watched together.
