“Skull Color” is a drawing that I did during my travels as well. I drew this one for my girlfriend. I'm not sure exactly where I was when I did it.  It took a lot longer than I thought it would. It is a very small drawing at only two inches by four inches. I used .005 color ink pens. I don’t have any hidden images in this one but the tiny property of it make it fun to look at just the same.
