This work titled 'Les Roses, Notations chromatiques' from the former Mira Jacob collection at le Bateau Lavoir (1920) combines watercolor, gouache, and pencil to explore floral and color relationships. The artist's notation-based approach suggests a focus on studying and recording chromatic variations and compositional possibilities. This piece reflects the experimental spirit of the early 20th-century artistic movements centered in Montmartre.
