This is one of my favorites too. I love this one because it has a good contrast. The paper is originally a white paper and it was colored in with a set of two black ink ballpoint pens. Yes it took two brand new pens to completely paint it black. If you look at this picture in person you can see the line by line strategy I used to color it, meaning that there are no random lines in the entire drawing. They all go from the top to bottom. In order to color the ribbon, I used color pencils and the unicorn itself is blue ink also from a ball point pen. Again, I don't remember what year I drew this one but it is also very old. This is the first time this picture goes on the internet for everyone to love or hate.
