Photo and fantastic analysis found here:
The appearance of Gorbachev vastly helps to raise Louis Vuitton's decadent image. Over the last decade, primarily because of the wide distribution of fake purses, the label’s image rapidly decay. The infamous monogram became a synonym of tackiness and bad taste - new rich people. As he appears using one of their bags, the label is instantly associated with high-power, great thinkers, and everything classy. A high-class sector of powerful men, and those whose intent is to become one of them, will probably be attracted by Louis Vuitton, and they will more likely start using them. Because after all, for most great thinkers, Gorbachev is like the Kate Moss of politics.
Me, I just think he looks more haunted/frightened than glamorous.
