Pencil sketch done one D size vellum of a Starter Gun, for starting races or training hunting dogs. I drew this in 1986 for an assignment when I was in school for Mechanical Drafting. We had to do a free hand sketch of an object with working parts. The drawing was left in my drafting portfolio and ended up in our garage, until a couple of days ago when my son brought my portfolio in the house and asked if it should be thrown out. I decided to scan this drawing, the vellum having creases in it showing up in the scan, I decided to tinker with it in MS paint and I kind of liked the look.
