Created for a HAM Radio/fountain pen guy --- this is a new model of his favorite radio designed for even further contact! It was drawn with a Pilot Custom Heritage 91 (F) using De Atramentis Document Ink Black on 140lb watercolor paper.
Here it is before the color.
Notice how waterproof the De Atramentis Document Ink is. There's no bleed at all. It's an outstanding ink for fountain pen artists.
