Modern illustrative ink work in the style of 20th-century pointillism

This monochromatic figurative artwork appears to be executed in black ink on a light-colored substrate, likely paper or canvas. The central subject is a distressed figure with a contorted facial expression, as if in the middle of a scream or emotional crisis. The figure's body is partially suggested through a dense network of swirling, scribbled lines and fine dotting. The background and the figure are integrated through a 'crackled' or venous pattern that radiates outward from the central motif. The craftsmanship displays a high level of detail, utilizing variations in line density to create value and form, highly consistent with detailed pointillist or stippling techniques. A small, stylized mark or signature is visible in the lower right corner, which is consistent with the user's claim that the work is signed 'Jane B.' The owner further identifies this work as an untitled piece ('Woman Freakin Out') by Jane Sablow, dated 1981, with dimensions of 27.5-inch by 39-inch. This user-provided attribution is currently unverified as physical inspection of the signature and substrate would be required for authentication. Overall, the work remains in good visible condition with a clean appearance and no apparent major tears or staining visible in the image.

Based on the provided image and description, I am evaluating a monochromatic ink drawing on what appears to be canvas, utilizing a detailed pointillist and stippling technique. The owner identifies this as an untitled 1981 work by Jane Sablow, noting it bears a mark interpreted as 'Jane B.' From a photographic review alone, I cannot physically inspect the substrate, the medium, or the signature firsthand. Therefore, this attribution remains a hypothesis. Physical examination and provenance research would be required to support authorship. Assuming the user's attribution to Jane Sablow is accurate, comparable modern pointillist ink works of this large scale (27.5 by 39 inches) by regional or mid-tier 20th-century artists typically sell in the $300 to $500 range at secondary market auctions. The intricate scribbling techniques and expressive subject matter add visual interest that supports this estimate. However, this valuation completely depends on the working assumption of the artist's identity. If this piece turns out to be an unattributed work, a student piece, or a decorative illustration in the style of the era, the market value would be strictly decorative, likely dropping to the $50 to $150 range. To properly evaluate the attribution, an in-person inspection by a specialist in late 20th-century illustration, along with a thorough review of past ownership documentation, would be strictly necessary.
