Hi Larry,

Thank you for contacting Mearto with your appraisal inquiry.
"Rock Hard" looks more like a signature to me though I've tried to find an artist whose name has some of those letters but haven't come up with anything but this is a very attractive painting of good size - not too big, not too small - and the market for Western American art is pretty strong at the moment.
Based on the photos and information provided, and subject to examination, this is:

Western American School, 20th Century
Western mountainous landscape
oil on canvas
inscribed "Rock hard"? lower left
canvas 36 by 48 inches; giltwood framed 48 by 60 inches
CONDITION: appears to be in good condition
PROVENANCE: acquired from a gallery or dealer
$800-1,200*
*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.
