How to describe this style of pencil art?

If you're looking for an &quot;art style&quot; wording, to describe it for example on a resume or on a commission service offer, I would say &quot;Pen-and-Ink Illustration for Advertising&quot; for example. Can you say with pencil? Sure. But Pen-and-ink is the better term for resumes (&quot;he who draws with ink, will draw with pencil&quot;).
Here is a great link for you to dive in, good luck mate!
