I did this sketch way back in college, but it fits the topic, so I'm posting it. When I was in high school, my grandpa gave me a folder of pictures from various magazines, newspapers, church bulletins, etc. that he had gathered. They were pictures that he thought would make interesting and challenging subjects for art. This image came from those pictures. I still have the folder and look at it from time to time for references and ideas.
The elephant is a quick sketch I did tonight, just to get some drawing time in. He fits the topic, so I'm posting him, too!
