Its graphic symbols, including quatrefoils and flowers (as well as the LV monogram), were based on the trend of using Japanese Mon designs in the late Victorian era. The patents later proved to be successful in stopping counterfeiting. In this same year, Georges travelled to the United States, where he toured cities such as New York, Philadelphia, and Chicago, selling Vuitton products.
