This is an oil painting on canvas board, measuring approximately 16x20 inches, depicting a dynamic seascape scene. The primary focus of the painting is a series of ocean waves crashing against a rocky coastline. The colors are vibrant and expressive, dominated by shades of blue and turquoise for the water, warm earthy browns and grays for the rocks, and a combination of light blue and soft pinks/purples for the sky and clouds. The composition is anchored by a significant rock formation on the left side, against which a large wave is depicted in mid-crash, creating white spray and foam. Further out, multiple layers of waves are visible, transitioning from deep blues in the distance to striking turquoise and aqua hues as they approach the foreground. The brushwork appears expressive, particularly in rendering the movement and texture of the water and clouds. There are discernible rocks in the foreground water, suggesting shallow coastal areas. The sky features large, billowy clouds with hints of pink and purple, indicating either dawn, dusk, or possibly just dramatic atmospheric conditions. Observable details include the apparent texture from the oil paint application, which adds depth to the waves and rocks. The overall condition appears to be good, with no obvious signs of significant damage, tears, or repairs visible in the provided image. The artist's signature, "M.C." for Mary Chesney, is visible in the lower left corner. The style suggests a representational, possibly impressionistic or expressive approach to landscape painting, and based on the medium and common practices, it likely dates from the 20th or 21st century.

AI Appraisal Report

·AI can make mistakes·Verify before acting
Based on my examination of the provided image and the owner's description, this oil painting on canvas board, measuring 16x20 inches, depicts a vibrant seascape. The condition appears good from the image, showing no obvious damage. The expressive brushwork and color palette suggest a representational style, possibly impressionistic, effective in capturing the movement of water. The discernible signature 'M.C.' for Mary Chesney is noted. Considering market conditions for contemporary representational landscape art by lesser-known artists, pieces of this size and subject matter typically fall into an accessible price range. While the painting is aesthetically pleasing, the artist's professional recognition and sales history are unknown, which significantly impacts value. Demand for marine art remains steady, but uniqueness and artistic mastery play a larger role in higher valuations. This piece is not rare in its subject or medium. My valuation is based on similar works by emerging or regional artists, where the decorative appeal and execution quality largely drive the price. Factors impacting value include the positive visual impact and apparent good condition. Without a established market for Mary Chesney's work, the value is primarily based on its inherent artistic merit and decorative appeal. It is crucial to note that this appraisal is limited by the visual information from images alone. Full authenticity verification would require in-person examination to confirm the medium, verify the artist's signature definitively, assess the true condition, and determine the precise age. Provenance documentation (e.g., bills of sale, exhibition records) would further strengthen authenticity and potential value, which cannot be assessed from images.
