Hello, this item is a large Asian folding screen painting, approximately 6 feet by 3 feet, featuring a continuous narrative landscape scene with figures, horses, architecture, and natural elements. Likely of Chinese or Japanese origin, these multi-panel screens (byōbu in Japan or pingfeng in China) traditionally serve both decorative and functional purposes, dividing spaces while showcasing delicate hand-painted or printed artistry. This particular screen appears to use soft pigments and minimalistic linework, characteristic of mid-20th-century decorative reproductions rather than antique hand-painted works.

Assuming it is a mid-20th-century decorative piece in decent condition, the estimated market value ranges between $300 and $700 USD. Antique or highly detailed, signed, or silk-painted screens can command much higher values, often exceeding several thousand dollars, but decorative versions from later periods are mainly valued for their size, craftsmanship, and visual impact. For a more precise assessment, especially regarding age and origin, I recommend consulting a specialist in East Asian decorative arts or an auction house familiar with Asian furniture and screens.
