This was an incidental design sketch for a scene, and it took off. I check my stats carefully, and this is one of my most viewed images. It goes to my ongoing pulp short story, The Mask of Dr. Satan: Die Like a Dog. I just wanted a 1930s style robot, where it was not clear if it was a man in a suit or a real robot. You be the fair jury. But Beware the Left Claw!
