Border Patrol (or, What to Do in the Event of a Wooly Mammoth Stampede)

This morning I did a lot of warmup sketches. But suddenly I began to think of Wooly Mammoths. Yes, that's right, Mammuthus primigenius, those terrific beasts from the Ice Age. I worked on other things. I tried to shake the thought of them, but there they were, stampeding through my brain, with savage Nordic warriors riding on top of them! So it was draw or be trampled. My pencil began to fly, and a quick sketch was made (bottom). I liked it, and so did the Mammoth (who thought he looked quite handsome), so I tore out a piece of tracing paper, transferred it to the Bristol, and the finished product was born. Now these rowdy fellows are immortalized on paper, along with their wall which is, of course, modeled after Hadrian's wall which I hope to visit next Summer. Let's hope this wall is better at keeping out smilodon and herds of Megaloceros giganteus than Hadrian's was at keeping out the Celts.
