The French fashion label Louis Vuitton had…
1858 CE
Louis Vuitton had observed that the HJ Cave Osilitee trunk could be easily stacked.
In 1858, Vuitton introduces his flat-topped trunks with trianon canvas, making them lightweight and airtight.
Until the introduction of Vuitton's trunks, rounded-top trunks have been used, generally to promote water runoff, and thus cannot be stacked.
It is Vuitton's gray Trianon canvas flat trunk that allows the ability to stack with ease for voyages.
Many other luggage makers will imitate LV's style and design.
