Dear Bonnie,

Thank you for the additional information. This is a watercolor or mixed media drawing because of the use of gouache. It has measurements of 13 1/2 x 9 1/2 inches and depicts a portrait of a woman with a hat. The drawing is signed in the right corner by the artist Nancy Anderson.
An estimation would be between 80 to 150 EUR.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
