Hi Alastair,

Thank you for contacting Mearto with your appraisal inquiry.
I think, after doing some research, that this is by Stan Hills rather than Steven Hills, who is not a listed artist.
Based on the photos and information provided, and subject to examination, this is:

Stan Hills (American, 20th Century)
Landscape with Cabin in the Forest and Snow covered mountains, n.d.
oil on canvas
signed lower right
35 x 24 inches
$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.
