Graphite drawing on paper, abstract cartographic style

This artwork is a detailed monochrome composition executed primarily in graphite on paper, presenting an abstract, map-like arrangement resembling an urban street grid or cartographic layout. The piece features intricate linework creating interconnected geometric shapes, pathways, and blocks, utilizing varying densities of shading ranging from stark white paper to deep, heavily saturated graphite blacks and mid-tone grays. The physical dimensions cannot be visually verified from the image alone, though the owner supplies measurements of 33 x 40 inches. There are no readily legible signatures, hallmarks, or maker's marks visible within the primary field of the image to confirm authorship from visual evidence alone. The condition appears well-preserved with clean edges and consistent tonal application, though this remains unauthenticated. The owner supplies additional unverified context attributing the piece to artist Myrel Chernick with the title 'Luxembourg/Montparnasse' and a date range of 2018-2021, which should be treated as unverified user-supplied claims rather than established fact. The overall aesthetic demonstrates meticulous attention to graphic pattern, spatial division, and textural contrast through pencil work.

Based on what I can see in the provided image and information, this monochrome composition presents an abstract, cartographic layout executed in graphite on paper, featuring intricate geometric linework and varying densities of shading. The owner supplies measurements of 33 x 40 inches and provides user-submitted claims attributing the piece to artist Myrel Chernick with the title 'Luxembourg/Montparnasse' and a date range of 2018-2021. I can't verify from a photo whether the attribution is correct, as I do not see a legible signature or maker's mark within the primary field of the image. My appraisal estimate of $3,000 to $5,000 assumes that the owner's attribution is correct and that the condition is excellent as reported. This valuation range is based on general market behavior for contemporary works on paper of similar scale and complexity. Demand for abstract graphite works varies depending on exhibition history and primary market standing. If physical inspection reveals that the item is a reproduction, replica, copy, or merely executed in the style of the artist rather than being an autograph work by Myrel Chernick, the value would decrease significantly, likely dropping to a decorative value range of $200 to $500. To thoroughly evaluate this piece and potentially support the attribution, physical inspection by a qualified paper conservator or art expert would be needed, alongside formal provenance documentation and exhibition records.
