The motif is composed of John McEnroe, the famous tennis player who introduced the world to Nike's cross-trainer shoe, the Air Trainer 1.

It has no name, and I love its mysterious existence. *The motif is composed of John McEnroe, the famous tennis player who introduced the world to Nike's cross-trainer shoe, the Air Trainer 1.
