In 2013, the valuation of the brand was US$28.4 billion with revenue of US$9.4 billion. The company operates in 50 countries with more than 460 stores worldwide. History Founding to World War II The Louis Vuitton label was founded by Vuitton in 1854 on Rue Neuve des Capucines in Paris. Louis Vuitton had observed that the HJ Cave Osilite trunk could be easily stacked. In 1858, Vuitton introduced his flat-topped trunks with Trianon canvas, making them lightweight and airtight. Before the introduction of Vuitton's trunks, rounded-top trunks were used, generally to promote water runoff, and thus could not be stacked. It was Vuitton's gray Trianon canvas flat trunk that allowed the ability to stack them on top of another with ease for voyages. Many other luggage makers later imitated Vuitton's style and design. The company participated in the 1867 Universal Exhibition in Paris. In 1871, Ōyama Iwao became the first recorded Japanese customer, ordering a set of luggage while in Paris as a military observer during the Franco-Prussian War. To protect against the duplication of his look, Vuitton changed the Trianon design to a beige-and-brown stripes design in 1876. By 1885, the company opened its first store in London on Oxford Street. Soon thereafter, due to the continuing imitation of his look, in 1888, Vuitton created the Damier Canvas pattern, which bore a logo that reads "marque L. Vuitton déposée", which translates into "L. Vuitton registered trademark". In 1892, Louis Vuitton died, and the company's management passed to his son. After the death of his father, Georges Vuitton began a campaign to build the company into a worldwide corporation, exhibiting the company's products at the Chicago World's Fair in 1893. In 1896, the company launched the signature Monogram Canvas and made the worldwide patents on it.
