Repoussé Metal Relief Plaque of Female Nude with Calla Lilies

This is a rectangular metal relief plaque, likely crafted through a hand-tooled repoussé and chasing technique. The central subject is a stylized female nude seen from behind, kneeling on a woven mat and reaching upward toward a dense, stylized arrangement of Calla Lilies. The material appears to be a thin sheet of pewter, tin, or perhaps silver-plated copper, which has been worked from the reverse to create a three-dimensional effect. The color is a monochromatic metallic silver tone with a heavy dark brown or black patina applied to the recessed areas to accentuate the depth and texture of the relief. The craftsmanship shows mid-20th-century stylistic influences, particularly the Art Deco revival movements of the 1960s or 70s. The composition utilizes flowing, organic lines for the female figure contrasted with the sharp, rhythmic repetition of the lily petals and the cross-hatched texture of the mat below. There are visible signs of aging including surface oxidation, minor scratches, and rubbing on the high points where the original finish has worn slightly. No clear maker's marks are visible on the front, suggesting it may be signed on the reverse or is a high-quality decorative workshop piece. The plaque is unframed with raw edges, indicating it may have once been mounted or intended for a custom frame.
