Well, everybody seems to enjoy Ken Anderson drawings. Here's more from his trip to South America (see below).
And here's an original from my personal collection. A few years ago I bought a packet of Ken's drawings that I think were from a project called "Scruffy" that never got made at Disney. It was about orangutans fighting on the side of the British during WWII. I don't know much more about it than that, but also in the packet were drawings of Nazi spiders. This was the only one I had framed because it was the only one in color. It was done with his usual Mont Blanc fountain pen - his tool of choice in that era. I scanned it through the frame, but it looks pretty good anyway. If I can find the rest of the drawings from that packet, I will scan them.
