By Lady Fox is a French stationery brand created in 2017 by Marie Bouin. The cards are printed at a Parisian printer on paper made in France. The By Lady Fox universe is colorful, sometimes childish and she conceives her illustrations as "little cocoons": situations or places where you feel good, you can find books, plaids, garlands, plants and steaming cups of tea. Apart from this stationery brand, Marie produces illustrations for companies and individuals and has notably produced illustrations for video lyrics of the singer and harpist Cécile Corbel.
