When I went to pick [artist Joe Zucker] up to photograph him, I didn’t recognize him. He has curly, blonde, bushy hair—but he had bought a jar of Vaseline, greased his hair down, borrowed someone’s white shirt and tie, someone else’s glasses, and he looked like a used car salesman. He understood that all he had to do was provide me with the evidence that someone like that existed for a 100th of a second. It didn’t necessarily have to be him.
