The painting depicts a mountainside landscape with trees rocks and meadows. It is signed W. Blackman" and this painting was made by the American artist William BLACKMAN who was active in San Diego, California, in the second half of the 20th century. He mainly depicted landscapes like these or maritime motifs in his art.
Works by this artist were recently offered and sold on the international auction market.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 250 to 500 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,
George
