French artist Georges Lucien Guyot (1885 - 1972) signed this charming woman nude study.
This painting features a lovely design of a woman getting out of the bath and wiping with a towel. Only a few lines in charcoal and red chalk or sanguine mark the silhouette and posture and capture the model's expression. The red color emphasizes the color of the skin and imbues the lascivious movement. The sketches of the bath towel are only suggested, but it gives the whole thing a lot of softness and an incredible illusion of movement.
Signed on the bottom left corner: Georges Lucien Guyot.
The artist used a technique named "sanguine," or red chalk or crayon. The drawing has a blood-red, reddish, or flesh coloration. It has been popular for centuries for drawing employed by 15th and 16th Century artists such as the great masters like Leonardo da Vinci, Michelangelo, and Raphael.
The drawing is ornate with a contemporary wood frame with a red and yellow deep-textured pattern and an off-white matte with acrylic glass protection.

About: 
Georges Lucien Guyot (born December 10, 1885, in Paris, where he died December 31, 1972) is a French artist, sculptor, and painter.
From an early age, Georges Guyot showed artistic abilities, but the modest conditions of his parents did not allow him to study art. So he did his apprenticeship with a wood sculptor. Guyot excelled in copying works from the 15th, 16th, and 17th Centuries but rapidly showed an attraction for nature. This attraction led him to the Jardin des Plantes in Paris, where he could study wild animals and translate his observations into sculptures and paintings.
A familiar figure of Montmartre, Georges Guyot was the guest of the Bateau-Lavoir from the time of Cubism. In 1931, he joined the group of Twelve, created by François Pompon and Jane Poupelet and which brought together sculptors such as Marcel Lémar, Paul Jouve, André Margat, Jean-Claude de Saint-Marceaux, and Georges Hilbert. After the end of WWII, he was elected mayor of the town of Neuville-sur-Oise. Very fashionable in his time, he had to wait until 1970 to have an exhibition devoted solely to his works.
He occupied Picasso's studio at The Bateau-Lavoir where he died on the last day of 1972.
