Abstract landscape composition in the mid-century modern style

This appears to be a large-scale abstract painting, likely oil or acrylic on canvas or panel, characterized by a cool-toned palette of sea-green, turquoise, beige, and slate grey. The composition suggests an abstracted landscape or coastal scene with a horizontal emphasis and vertical dripped elements on the left side. The application of paint is expressive and textural, utilizing both broad washes and impasto techniques with visible scumbling and scratching through layers (sgraffito). The lower right corner bears a stylized monogram or initials consistent with a 'TB', as noted by the user; however, this marking remains unverified without physical inspection and provenance documentation. The work is stylistically consistent with late 20th-century or contemporary abstract expressionist movements, prioritizing atmospheric mood over figurative detail. Several surface abrasions and minor scuffs are visible, particularly near the edges and the lower right quadrant. All attributions, including those related to the visible initials, are hypothetical and subject to professional in-person authentication to determine the specific artist and age.

I have examined the digital image of this large-scale abstract landscape. Based on what I can see, the work displays a palette and gestural technique consistent with mid-to-late 20th-century abstract expressionism. Per user submission, the piece is attributed to an artist with the initials 'TB', as a stylized monogram is visible in the lower right; however, I cannot verify the identity of the artist or the age of the materials from a photograph alone. The value estimate is predicated on the hypothesis that the 'TB' marking corresponds to a listed artist with an established secondary market. If the attribution is correct and the work is a period piece in good condition, comparable works of this scale and atmospheric quality typically occupy the higher end of the provided range. Physical inspection would be required to assess the substrate and paint layers for signs of age and to confirm if the scuffs and abrasions are superficial or require professional conservation. I cannot determine from a photo if the signature was added later or is integral to the paint layer. To move beyond this working assumption, one would need provenance documentation, such as a gallery receipt or exhibition history, and an in-person examination by a specialist. If the work is found to be unattributed, a contemporary 'in the style of' piece, or by an unlisted decorative artist, the fair market value would significantly decrease, likely falling into the $300–$600 range. The current market for mid-century modern aesthetics remains strong, but value is highly dependent on verifiable authorship.
