AI Appraisal Estimate

This item is a portrait sketch of a Native American man, identified by the user as Leland Winter. The artwork is rendered in a monochromatic sanguine or terracotta-toned medium, likely conte crayon, pastel, or colored pencil, on a heavy white or off-white paper stock. The composition features a bust-length frontal view of an older man with weathered facial features, deep-set eyes, and long dark hair held back by a headband. The artistic style is a blend of realism and expressive sketchy line work, particularly visible in the rendering of the hair and the chest area. The piece is signed 'DuBois' in the lower right area of the drawing field in a stylized script, with a second, simpler 'DuBois' notation at the bottom right corner of the sheet. The paper appears to be in good condition with no visible foxing or significant creasing, although the lighting in the image suggests a slight texture to the paper. The craftsmanship exhibits a high skill level in capturing anatomical accuracy and human emotion, likely dating from the mid to late 20th century. The piece represents a typical example of Western or Indigenous portraiture popular in the American Southwest and Pacific Northwest art markets.

Based on my examination of the submitted image, this portrait of Leland Winter by the artist DuBois represents a high-quality example of Mid-Century Western/Indigenous portraiture. The work, executed in a sanguine-toned medium (likely Conté crayon), demonstrates exceptional draftsmanship, particularly in the structural rendering of the sitter's facial anatomy and the expressive, rhythmic handling of the hair. The condition appears to be excellent, with the paper retaining its structural integrity and showing no visible evidence of UV-induced fading, foxing, or environmental staining. Market-wise, works by 'DuBois' (frequently associated with Guy DuBois or regional specialists in Western portraiture) hold steady appeal for collectors of Americana and Indigenous subjects. This specific piece derives value from its sensitive portrayal of an identified subject, Leland Winter, which elevates it above generic ethnographic character studies. Comparables for similar mid-sized charcoal or sanguine portraits on paper by regional masters typically realize between $400 and $800 at specialized art auctions in the American Southwest. Limitations: This appraisal is based strictly on digital photographic evidence. A formal authentication would require an in-person inspection to verify the paper's watermark, determine if the medium is fixed, and rule out any sophisticated reproductive techniques (such as a high-quality lithograph or giclée). Authenticity is currently inferred from the signature and stylistic consistency. Full valuation would further benefit from provenance documentation—such as a gallery label or bill of sale—confirming the circumstances of the commission and the artist's specific identity within the DuBois lineage.
