Pen & Ink was at one time, not only a great sketch tool, but also the only method for CAD. Such as the first Illustration shown, which is overlayed with zipatone, as is the second drawing of Lexington. The owl is two separate drawings, one black ink only, the other in colored ink. The UKJE-Cruisin CD cover is a finished print done with 3 layers of Pen & Ink directly on acetate. The Mixed Media page contains other versions of drawings here, that were colorized by airbrush or watercolor.
