This is one of three proof prints I recently bought at an Estate Sale in Canaan, CT. All are by Georgia O’Keefe. Unsigned( of course) printers proofs. Silkscreen? The other titles are “Sunflower” and “Blue and Green Music.”
Image size is 14” x 11 1/2”. Paper size is 20” x 17 1/2”.
I know nothing about it.
Thank you for your help and patience.
The presented object appears to be a lithograph in colors on paper with the measurements of 20” x 17 1/2”. The print depicts a flower and is titled in pencil "Black Iris". This print was made after a painting by Georgia O'Keefe (https://www.metmuseum.org/art/collection/search/489813). Because of the fields with the test colors, this is a proof print before a larger edition. There is no authetificated print of the Black Iris painting by O'Keefe known. It is questionable if this is a print by O'Keefe or after the painting by another artist. The handwriting reminds me more or less of the handwriting of O'Keefe but this is a weak argument for attribution.
Comparable objects were recently not offered and sold on the international auction market. This piece is in good condition and there is no serious damage visible in the images provided.
Fair market estimation for an authenticated print would be between 500 to 1.000 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.
With kind regards,
