Mixed-Metal Verdigris Southwestern Shield Wall Sculpture

This is a large, circular wall-mounted decorative sculpture crafted in a contemporary Southwestern or Brutalist style. The piece is constructed from heavy-gauge copper and brass sheet metal. It features a prominent convex shield shape as the base, heavily treated with a vibrant turquoise verdigris patina that shows deep tonal variations and intentional oxidation. Centered on the shield is a multi-layered, stepped geometric 'Sun' or 'Star' motif rendered in untreated brass with a lighter patina, creating a three-dimensional relief. The surface is further embellished with stamped or chased zigzag patterns and tribal-inspired borders. Three metallic, feather-shaped finials extend from the top, while twisted brass ribbons cascade down the sides, simulating leather fringe. The craftsmanship suggests a studio art piece from the late 20th century (circa 1980s-1990s). The condition appears good with intentional distressing; however, there are visible scuffs on the patina and some oxidation spots on the brass elements. No maker's mark is visible in the provided image, but the quality of the welds and the complexity of the chemical patina indicate professional artisanal production.

Based on my examination of this Mixed-Metal Verdigris Southwestern Shield, I have assessed it as a high-quality studio art piece likely produced during the peak of the Santa Fe Style movement of the late 1980s and early 1990s. The piece exhibits sophisticated chemical patination and skilled metalwork, particularly in the brazing and layering of the central brass solar motif. The use of heavy-gauge materials and the complex interplay of the turquoise verdigris against the warm brass tones suggest a professional artisanal origin rather than mass-market manufacturing. Condition is consistent with age; while the distressing is largely intentional to achieve a weathered tribal aesthetic, there are minor scuffs and unintended oxidation spots that slightly detract from a 'mint' valuation. Market demand for Southwestern Brutalist metalwork remains steady, though it is currently niche compared to Mid-Century Modern aesthetics. Comparables for unsigned artist-made shields of this scale typically realize between $400 and $850 at boutique auctions or specialized galleries. Critically, the absence of a maker’s mark limits the valuation; if this were attributed to a known artisan such as metalist Sergio Bustamante or a specific Sedona-based studio, the value could double. Because this appraisal is based on digital imagery, I cannot definitively verify the weight or the integrity of the rear mounting hardware. A full authentication would require an in-person physical inspection to examine the weld points for specific 'hand-writing' styles of known artists, provenance documentation (original gallery receipts), and a chemical analysis of the patina to ensure modern synthetic sprays weren't used to mimic authentic oxidation.
