Hi Lydia

Thank you for contacting Mearto with your appraisal inquiry.
Carrington's works bring prices across a broad range and are enjoying a moment now with the surging interest in Latin American works. If you opt to sell this painting at auction, you may benefit from selling it in a sale dedicated to Post-Impressionism and/or Latin American fine art. It also looks like there is signature on the lower right corner but it's hard to see. Given the potential value of this, my appraisal is conditional and I would recommend having this authenticated.
Based on the photos and information provided, and subject to examination, this is:

Leonora Carrington (United States, Mexico, France, 1917-2011)
Untitled dreamscape portrait of a female figure with large white birds
oil on canvas
inscribed and labeled on the verso
26 by 22 inches, framed
CONDITION: appears to be in good condition
PROVENANCE: B. Lewin Galleries
$150,000-250,000*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Because your item has a fair market value of at least $5000 and you indicated an interest in selling it, one of our representatives will reach out by email in the next day or two to provide some information on options for consignment and sale. If you have any questions in the meantime, please just let me know.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
