Carl Buell, who illustrated many lovely critters for my new book The Tangled Bank, has been adding some new paintings to his Flickr stream. Here's his holiday ground sloth. In the caption, he writes: "I've certainly drawn and painted enough of them over the past 15 years. Ground sloths are a favorite subject. Too big to hide from the weather, this big guy just hunkered down and slept through the storm. It's hard to imagine these guys in snow, but Megalonyx ranged as far north as Alaska. Another Card idea that never got off the ground." Card or not, I'm glad he's sharing his handiwork.
