Ink architectural drawing signed 'Frank Green'

This artwork is a detailed architectural ink drawing executed on heavy off-white paper, measuring roughly standard page proportions. The drawing depicts an elaborate Gothic Revival church building with a prominent central steeple and slender spire dominating the composition, positioned at an urban intersection. To the left and right, surrounding streetscapes featuring domestic and commercial buildings are rendered with fine hatchwork and cross-hatching to denote texture, shadow, and masonry depth. The medium appears to be black ink, possibly applied with a fine-nib pen, utilizing precise lines to capture the stone detailing of the primary structure. Condition-wise, the paper displays minor surface smudges, faint handling wear along the edges, and two pre-punched binder holes on the left margin, indicating it was likely stored in a ring binder or portfolio. At the bottom left, handwritten text reads 'ST. CUTHBERT'S CHURCH / EVERTON.', and at the bottom right, a signature and date read 'Frank Green / 1979.' (unverified). The owner's unverified notes suggest the subject is St. Cuthbert's Church in Everton. The attribution to Frank Green rests entirely upon the legible handwritten signature at the lower right corner, which is unverified and has not been authenticated. The stylistic qualities of the linework and architectural subject matter are consistent with late 20th-century topographical illustration.

Based on what I can see in the provided image, this artwork is a detailed architectural ink drawing on heavy off-white paper, depicting a Gothic Revival church identified by the user as St. Cuthbert's Church in Everton. Per user submission, the piece bears a signature and date reading 'Frank Green / 1979.' at the lower right. I can't verify from a photo whether the signature is autograph or whether the attribution is correct, as visual inspection alone cannot rule out facsimile or studio production. Based on the assumption that this is an authentic late 20th-century topographical ink drawing by the named hand, the estimated market value is $300-$500. This range reflects current general market demand for similar architectural works on paper, which typically trade modestly unless associated with an artist of major institutional renown. Condition factors such as minor surface smudges, edge wear, and two pre-punched binder holes on the left margin moderately detract from the overall value. Would need physical inspection to confirm paper quality, ink application, and the nature of the signature. Furthermore, establishing provenance documentation or consulting a specialist would be necessary to further support the attribution. If the piece turns out to be a reproduction, copy, or produced 'in the style of' rather than an autograph work, the value would decrease significantly, typically falling into the $50-$150 decorative range.
