The title is “Blanche Painting with her Sister Suzanne on the Water Side”. It was painted in 1887 by Claude Monet.
Blanche was the daughter of Monet’s second wife Alice. She became his daughter-in-law by marrying Jean Monet, the painter’s eldest son.
Blanche was a talented artist. She often painted the same landscapes as Monet, in her own impressionist style, sometimes very similar to the style of the master.
Her sister Suzanne appears on numerous canvases, because she was a pretty young woman. Monet had her posing for his two attempts of a figure in open-air, aka as the girl with a parasol. (Musee d’Orsay, Paris)
