Cleanroom Sketchbook

These pictures are from a very strange sketchbook that I kept while I was working in a cleanroom, a factory where you have wear a special suit to reduce lint and static electricity. They use special paper in cleanrooms, it feels like it's made of plastic and it doesn't shed lint. I drew all of these with a ball point pen - not my favorite medium - but I like some of the drawings. There is a long ugly section of people eating, those are called Pie Hole I, Pie Hole II, etc... The drawings area about 2" x 6"
