SHANGHAI — At the opening of the exhibition "Salvatore Ferragamo: Evolving Legend 1928-2008" on Friday at the Shanghai Museum of Contemporary Art, the biggest crowd-pleaser wasn't the collectable bags, the chandelier of perfume bottles, the walls of shoes, or even the vintage footwear that had been worn by Hollywood icons like Mary Pickford, Douglas Fairbanks, Elizabeth Taylor and Marilyn Monroe. Rather, it was the workshop, where craftsmen worked away on bags, belts and shoes displaying the various states and steps of their production.
