Large vintage painting from the 50s-60s, oil on panel, original and unsigned, to be identified. Landscape format, nude woman lying down. Modern style, non-academic 20th century, figurative, beautiful technique, lovely nuances of colors in the background and skin, nice slightly dreamy work. Unframed, size 65x54cm, 3mm thick. Generally in good condition, some signs of wear over time, particularly in the corners and edges, a few discreet marks or scratches, a vertical black line on the right side of the painting, original, a few brush hairs in the paint slightly visible. Weighs about 1kg, no attachment on the back. Possibly related to a small lot of works by the same unidentified artist, with a unique and sensitive style, typical of the figurative modernity of the 50s-60s.
