HEIST ALARM: To mark the launch of the new Damier Graphite collection for men, Louis Vuitton cooked up a novel window display concept. The company’s Fifth Avenue flagship in New York currently features two windows with the bag in a museum-like glass case, surrounded by chrome and metallic security cameras pointing at it. The adjacent windows show the same scenario, except with the cases broken into, glass shards on the floor, the bags missing and the security lasers activated. While it makes for great viewing pleasure, the concept apparently proved too real for some. Last Wednesday morning, police officers entered the boutique to investigate the broken glass.
