This is the back of my "art folder" where I keep all of the drawings in progress, finished, and abandoned. When I first starting using a folder for this purpose, I just had a plain white folder, so I started doodling on the back, a bunch of little chibi characters. As that folder fell apart, I had to replace it, and went with another white folder, specifically so I could draw something on the back.

Every folder since then has had something drawn and colored with pencils on the back, and this is just the latest addition to the series. I'm sure a year from now I'll be replacing this one just the same, and the cycle will start again.
