When Mark Twain's autobiography was released - it was held untill 100 years after his death for release - I saw this image of him. I believe that this is the image from the cover of the autobiography. I forget how I came about it, but for whatever reason, I thought that the eyes alone were amazing so I cropped the image to this format and I found that the character still remained. As usual, I became obsessed, and had to create a digital charcoal based on the cropped photo.
