I'm not sure what the exact sequencing of these images is, or what order Sienkiewicz completed them. But it appears to be a transition of his Bob Peak influence into his own visual language by the end. There's a piece that looks to be a nod to Robert McGinnis tucked in as well. In Sienkiewicz, we get an illustrator who's a post-modern mix master of the history of American illustration. He seems to be drawing from many historical sources, then redefining them, changing their context, and making them his own, blending them into an unmistakable signature style so that you forget the past. It's a hip-hop approach to painting.
