Invention is a 14″x17″ pen and ink drawing, drawn using a .25 mm Rapidograph pen and ink. The initial design was created using a pencil, compass, ruler and protractor. After creating an initial drawing concept in pencil, I drew all of the detail with ink. I scanned the original image then inverted the color to create a negative image. All shapes are drawn completely freehand. This drawing is available in 8×10, 11×14, and 16×20 archival quality prints. The 16×20 print has the same dimensions as the original drawing, just printed on slightly larger paper.
