Fairly large vintage painting from the 50s-60s, oil on canvas board, original and unsigned. Vertical format, portrait of a seated woman with an innocent gaze. Modern style, School of Paris, or regional school of Loir et Cher, post-Fauvist, post-impressionist, beautiful technique, very nice color nuances in the background and in the skin tones. Unframed, size 55x46cm, 4mm thick. Very good overall condition, slight wear from time with no major visible defects except for a slight deformation of the board, bulging backward in the center, discreet. Weighs approximately 900g, no back attachment. Part of a small lot of works by an unidentified artist, with a unique and sensitive style typical of the figurative modernity of the 50s-60s.
