Hi Thomas,

Thank you for contacting Mearto with your appraisal inquiry.
I've not found a match for that style or signature in a search of artists with the last name of Evans; it may be that they had a limited production and no records of works sold at auction. I'm also not coming up with any matches when I cross reference the Art Institute of Chicago.
Based on the photos and information provided, and subject to examination, this is:

American School, 20th Century
Untitled Still Life: table by open window with goldfish bowl, vase of flowers and bowl of fruit
undated
oil on canvas
18 by 24 inches
signed EVANS lower left
PROVENANCE: acquired at the Pebble Beach Gallery, Monterey, Calif.
$300-500*
*represents a fair-market value for auction purposes; retail or asking price may vary.

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