Android Cave Bear
One of my earliest "fake product" illustrations. An android cave bear. I did a ton of research on cave bears and the metal skull is a perfect replica of an actual cave bear skull. It turns out that cave bear skeletons and skulls were the origins of dragon mythology.
Cave bears went extinct when neanderthalls ruled the earth. Most likely it was man who drove them to their extinction. However long after they died off more modern man found their bones in caves. They had no idea what they were and since there were many other bones in these caves from the prey they ate men made up stories about what these creatures were. That is most likely where the legends of dragons came from.
