Though it has retail locations all over the globe, Tiffany & Co.’s flagship store at 727 Fifth Avenue in New York City is as much a part of the brand as silver. Opened in 1940, featured in the iconic Breakfast at Tiffany’s, and beset with a granite and limestone facade, it has served as a backdrop for countless films and host to countless pre-engagement sweats. Tiffany & Co. The Landmark celebrates one of commerce’s great ladies in detail, from its early history to its recent rooftop renovation.
