Before computers I had to hand letter 100 3x8 banners for Dutch Boy Paint. They had the dutch boy sitting on a swing stage with a brush and can of paint logo, all dark blue. We hung them from the cieling to dry and after painting about fifty of them I took a break. While I was out an employee took some paper and cut out small circles and colored them blue, then stuck them on the face of the dutch boy making the eyes cross eyed on about the last 20 or so. When I returned he and some other employees sayed, hey, come here and look what you did. You made a bunch of these things cross eyed! I looked and thought how could I have done that. Well I got out a quill and went to fix them and noticed that it was just colored paper, we all had a good laugh.
