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.
