It’s a Samuel L. Jackson caricature, drawn shortly after Revenge of the Sith came out. We were all used to seeing bald Sam in a robe frowning at Jedis and speaking in a calm, measured tone. This ain’t your Snakes on a Plane Samuel L.
If I remember right, this was when I was trying to work out how to use skim light and white space most effectively. When done right, it can look pretty cool and three-dimensional, and it makes a big difference when drawing someone dark. You can see at least two skin tones blended together on all the colored areas of his face, and skipping those to leave it white is a real time saver. But when I was trying to figure it out, a lot of customers, mostly kids, would say: “Why’d you leave that part white? You forgot to color it there!” So this drawing, I think, was the first time I really left a lot of white space on a black man’s face and was happy with the result. And no kids have complained about it either.
