Leland Cook was the in-house photographer with Tiffany & Co. in Manhattan from the late 1950s until the 1980s. During filming, Cook was permitted to take informal shots of Audrey Hepburn, other cast members and film crew milling around for his own personal records.

In her autobiography Of Diamonds & Diplomats, Letitia Baldridge, Tiffany's former Executive Director of Publicity, recalls the exciting period when Hollywood descended onto Fifth Avenue in the autumn of 1960...."The group included young director Blake Edwards and his uncountable camera and technical crew, Audrey Hepburn, George Peppard, hairdressers, stylists, cosmeticians, wardrobe mistresses and Miss Hepburn's small but yapping dog. Charles L. Tiffany would have been astounded to know that his private diamond room...was transformed into a glamorous movie star's dressing room.....The crew worked in Tiffany's from Saturday evening to Monday morning...they used the store the following weekend as well". Of the famous opening sequence she recalls that the windows were problematic for the lighting crew and had to be changed seven times ...The scene was shot at dawn..with all of us helping the police halt traffic at the intersections when the actual takes were made. The streets of New York are never deserted. Miss Hepburn did the walking scene over and over and over again in her sleeveless dress...her arms covered by a mass of goosepimples from the chill.....The entire store was in a perpetual state of excitement over the filming for two weeks....The movie and television reruns have continued to be seen by millions all over the world, and every month tourists come into the store and ask where the restaurant is."

The necklace worn by Hepburn in the photograph illustrated here incorporates the famous Tiffany Diamond, and was desgined by Jean Schlumberger.
