Le Petit-Beurre de LU was invented in #Nantes in 1886 by Louis Lefèvre-Utile.
It wasn't until 1888 that its design and trademark were registered before the Nantes Commercial Court.
To this day, this Nantes biscuit remains one of the most famous in France.
For the curious, INPI is currently hosting an exhibition entitled "Des Marques à l'affiche".
