The past weekend was the last opportunity for people in New York to see the Chanel Mobile Art in Central Park. A futuristic nomad art centre imagined by Karl Lagerfeld and designed by Zaha Hadid to celebrate the anniversary of Chanel’s 2.55, the very same iconic quilted bag that warranted a double spread on Wally’s latest book, and so named because it was first issued in February 1955. I took the A train uptown to see what this was about.
