Its luggage is among the most famous and prestigious in the world, a standard accessory aboard the first-class cabins of aircraft flying transatlantic and transpacific. Not content to cover the world's luggage with his initials, Vuitton has branched into leather goods, writing instruments, travel products, and publishing.

The mezzanine showcases upscale pens, writing supplies, and stationery. And the top floor carries the company's newest line -- women's shoes and bags.
