My first visit to the Pompidou Centre. It hadn’t existed during my last trips to Paris in 1969 and 1972. So I was doubly mesmerized by both the busyness of the structure’s tunnels and scaffolding, and by the tribute to Martin Scorsese. I remember showing this photo to my colleague Ed, a Scorsese fan. His very first reaction was, “Look at that pigeon!” I had no idea what he was talking about and I’d seen this photo dozens of times. Then I took a closer look. Can you see it?
