Dear Steven,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil or acrylic paint on canvas with 60 x 80 cm measurements. The painting depicts a landscape with threes and a lake and a mountainside in the background. It was made and signed by Dalhart Windberg (Texas, b.1933) who mainly depicted landscapes in his art.
Comparable objects were recently offered and sold mainly on the American auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 2.500 to 5.000 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,
Gregory
