"voluptuousness" watercolor and mixed technique by louise percheron (early xx)

Bouquet of roses in a unique technique mixing watercolor at the base with pigmentation additions (floral?). Work made by an artist of the early twentieth century. Louise bergeron was in the same line of artists such as blanche odin especially since they both made paintings mainly around the floral world and particularly roses. With the difference that louise bergeron used pigments directly on the painting giving an abstract effect as well as impressionist. In a period setting in poor condition bearing an old sales label and on the back a dedication for the artist.
