Dear Yassine,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil or paint on canvas with 9,5 x 11,5 inches measurements. The painting depicts an abstract geometrical composition and is signed in the lower right. The style and the signature could be compared with other works by the artist Nicolas DE STAËL
(1914-1955). In comparison to other works the composition of this artwork appears a bit weak.
Nicolas de Steël, a French painter of Russian origin, was a follower of the artistic movement of Informalism.

Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation for an authenticated artwork by Nicolas de Stael would be between 250.000 to 500.000 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

Because of its high value, this artwork needs further authentication.

With kind regards,
Gregory
