The last line is the address of the flagship store in Paris, isnt' it?
Inventeur = inventor?
I don't really understand the first line, mainly because I don't know what the verbs déposer and l'étranger are in English, anyways, I typed it in a French-English translator online and got this:
"deposited in France and abroad"
SO the whole thing is...
"Deposited in France and abroad
LOUIS VUITTON
Inventor
101 Avenue of Champs-Elysées, Paris"
Fluent French speakers, anyone?
